Check Digit Verification of cas no

The CAS Registry Mumber 6453-98-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,5 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6453-98:
(6*6)+(5*4)+(4*5)+(3*3)+(2*9)+(1*8)=111
111 % 10 = 1
So 6453-98-1 is a valid CAS Registry Number.

Destannylative acylation of 1-[(2-methoxyethoxy)methoxy]-2- (phenylsulfonyl)-2-(tributylstannyl)cyclopropane: A novel route to 3- acylfurans

Pohmakotr, Manat,Takampon, Auntika

, p. 4585 - 4588 (1996)

Destannylative acylation of 1-[(2-methoxyethoxy)methoxy]-2- (phenylsulfonyl)-2-(tributylstannyl)cyclopropane (1) provided dihydrofurans 5 in good yields, which upon treatment with BF3.OEt2 in CH2Cl2 led to the formation of 3-acylfurans 6 in moderate yields. The reaction was proposed to proceed via the intramolecular Prins-type reaction of the oxonium intermediate 7.

Mechanochemical Solvent-Free Suzuki–Miyaura Cross-Coupling of Amides via Highly Chemoselective N?C Cleavage

Ma, Yangmin,Shao, Lei,Szostak, Michal,Wang, Ruihong,Zhang, Jin,Zhang, Pei

supporting information, (2022/01/04)

Although cross-coupling reactions of amides by selective N?C cleavage are one of the most powerful and burgeoning areas in organic synthesis due to the ubiquity of amide bonds, the development of mechanochemical, solid-state methods remains a major challe

Palladium-Catalyzed Amide N-C Hiyama Cross-Coupling: Synthesis of Ketones

Idris, Muhammad Aliyu,Lee, Sunwoo

supporting information, p. 9190 - 9195 (2020/11/18)

N-Acylglutarimides and arylsiloxanes reacted in the presence of Pd(OAc)2/PCy3, Et3N·3HF, and LiOAc to provide the corresponding arylketones in good yields. Aryl-, vinyl-, and alkyl-substituted N-acylglutarimides showed good activity in the coupling reactions of arylsiloxanes. The reaction had a broad substrate scope and showed good functional group tolerance. N-Benzoylsuccinimide and N-protected N-phenylbenzamides showed good activities in coupling reactions with phenylsiloxane. The employment of CuF2 as an activor afforded the decarbonylative products at 160 °C.

N-Acylcarbazoles and N-Acylindoles: Electronically Activated Amides for N-C(O) Cross-Coupling by Nlpto Ar Conjugation Switch

Buchspies, Jonathan,Rahman, Md. Mahbubur,Szostak, Roman,Szostak, Michal

supporting information, p. 4703 - 4709 (2020/06/17)

The development of new amide precursors for selective, catalytic activation of carbon-nitrogen bonds in amides is a fundamental objective of this emerging reactivity manifold. We report the palladium-catalyzed Suzuki-Miyaura cross-coupling of N-acylcarbazoles and N-acylindoles with arylboronic acids by a highly selective N-C(O) cleavage. The key amide bond ground-state destabilization stems from Nlp to Ar conjugation and enables us for the first time to achieve reactivity similar to that for N-acylsulfonamide and N-acylcarbamate activation in simple anilides.

Fukuyama Cross-Coupling Approach to Isoprekinamycin: Discovery of the Highly Active and Bench-Stable Palladium Precatalyst POxAP

Tang, Shuang-Qi,Bricard, Jacques,Schmitt, Martine,Bihel, Frédéric

, p. 844 - 848 (2019/01/30)

An efficient and user-friendly palladium(II) precatalyst, POxAP (post-oxidative-addition precatalyst), was identified for use in Fukuyama cross-coupling reactions. Suitable for storage under air, the POxAP precatalyst allowed reaction between thioesters and organozinc reagents with turnover numbers of ~90000. A series of 23 ketones were obtained with yields ranging from 53 to 99%. As proof of efficacy, an alternative approach was developed for the synthesis of a key precursor of the natural product isoprekinamycin.

Pd-PEPPSI: Water-Assisted Suzuki?Miyaura Cross-Coupling of Aryl Esters at Room Temperature using a Practical Palladium-NHC (NHC=N-Heterocyclic Carbene) Precatalyst

Li, Guangchen,Shi, Shicheng,Lei, Peng,Szostak, Michal

supporting information, p. 1538 - 1543 (2018/03/01)

A Pd-PEPPSI-catalyzed (Pd=Palladium, PEPPSI=pyridine-enhanced precatalyst preparation stabilization and initiation) Suzuki-Miyaura cross-coupling of aryl esters via selective C?O cleavage at room temperature is reported. The developed catalyst system displays broad substrate scope with respect to both components under practical ambient reaction conditions using readily-available, cheap, modular, air- and moisture-stable Pd-NHC precatalyst (NHC=N-heterocyclic carbene). The use of water proved crucial for achieving high reactivity in this coupling. The catalyst system represents the mildest conditions for the Suzuki?Miyaura cross-coupling of aryl esters reported to date. The protocol also allowed for achieving TON >1,000 (TON=turnover number) in the Suzuki?Miyaura ester coupling for the first time. (Figure presented.).

Rapidly Activating Pd-Precatalyst for Suzuki-Miyaura and Buchwald-Hartwig Couplings of Aryl Esters

Dardir, Amira H.,Melvin, Patrick R.,Davis, Ryan. M.,Hazari, Nilay,Mohadjer Beromi, Megan

supporting information, p. 469 - 477 (2018/02/19)

Esters are valuable electrophiles for cross-coupling due to their ubiquity and ease of synthesis. However, harsh conditions are traditionally required for the effective cross-coupling of ester substrates. Utilizing a recently discovered precatalyst, Pd-catalyzed Suzuki-Miyaura and Buchwald-Hartwig reactions involving cleavage of the C(acyl)-O bond of aryl esters that proceed under mild conditions are reported. The Pd(II) precatalyst is highly active because it is reduced to the Pd(0) active species more rapidly than previous precatalysts.

Acid fluorides as acyl electrophiles in suzuki–miyaura coupling

Ogiwara, Yohei,Sakino, Daisuke,Sakurai, Yuka,Sakai, Norio

supporting information, p. 4324 - 4327 (2018/08/28)

The first palladium-catalyzed construction of ketones through Suzuki–Miyaura reaction by using acid fluorides is described. In contrast to typical acyl electrophiles such as acid chlorides, acid fluorides are uncommon acyl electrophiles to use in boron-based coupling reactions, probably due to a high level of stability toward nucleophiles. This first attempt to use acid fluorides as a coupling partner with boronic acids allowed highly functional group tolerance and a wide substrate scope while affording various ketones in effective yields.

General Method for the Suzuki-Miyaura Cross-Coupling of Primary Amide-Derived Electrophiles Enabled by [Pd(NHC)(cin)Cl] at Room Temperature

Lei, Peng,Meng, Guangrong,Ling, Yun,An, Jie,Nolan, Steven P.,Szostak, Michal

supporting information, p. 6510 - 6513 (2017/12/26)

A general, highly selective method for the room temperature Suzuki-Miyaura cross-coupling of commonly encountered primary benzamides is reported. A combination of site-selective N,N-di-Boc-activation (tert-butoxycarbonyl activation) of the amide nitrogen with practical air- and moisture-stable, well-defined, and highly reactive [Pd(NHC)(cin)Cl] (NHC = N-heterocyclic carbene; cin = cinnamyl) provides a highly effective route to biaryl ketones from primary amides in high yields. For the first time, a TON of >1000 has been achieved in amide acyl cross-coupling.

N-Acylsuccinimides: Twist-controlled, acyl-transfer reagents in Suzuki-Miyaura cross-coupling by N-C amide bond activation

Osumi, Yuki,Liu, Chengwei,Szostak, Michal

supporting information, p. 8867 - 8871 (2017/11/09)

The palladium-catalyzed Suzuki-Miyaura cross-coupling of N-acylsuccinimides as versatile acyl-transfer reagents via selective amide N-C bond cleavage is reported. The method is user-friendly since it employs commercially-available, air-stable reagents and catalysts. The cross-coupling is enabled by half-twist of the amide bond in N-acylsuccinimides. These highly effective, crystalline acyl-transfer reagents present major advantages over perpendicularly twisted N-acylglutarimides, including low price of the succinimide activating ring, selective metal insertion under redox neutral conditions and high stability of the amide bond towards reaction conditions. Mechanistic studies indicate that oxidative addition is the rate limiting step in this widely applicable protocol.
