Check Digit Verification of cas no

The CAS Registry Mumber 29514-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,5,1 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 29514-68:
(7*2)+(6*9)+(5*5)+(4*1)+(3*4)+(2*6)+(1*8)=129
129 % 10 = 9
So 29514-68-9 is a valid CAS Registry Number.

A Photocatalytic Regioselective Direct Hydroaminoalkylation of Aryl-Substituted Alkenes with Amines

Larionova, Natalia A.,Ondozabal, Jun Miyatake,Smith, Emily G.,Cambeiro, Xacobe C.

, p. 5383 - 5388 (2021)

A photocatalytic method for the α-selective hydroaminoalkylation of cinnamate esters has been developed. The reaction involves the regioselective addition of α-aminoalkyl radicals generated from aniline derivatives or aliphatic amines to the α-position of unsaturated esters. The scope of aromatic alkenes was extended to styrenes undergoing hydroaminoalkylation with anti-Markovnikov selectivity, which confirms the importance of the aromatic group at the β-position. Simple scale-up is demonstrated under continuous flow conditions, highlighting the practicality of the method.

Copper-Catalyzed B(dan)-Installing Allylic Borylation of Allylic Phosphates

Yoshida, Hiroto,Murashige, Yuya,Osaka, Itaru

, p. 2286 - 2290 (2019)

γ-Selective B(dan)-installing allylic borylation was found to proceed efficaciously by the reaction of an unsymmetrical diboron, (pin)B?B(dan), with allylic phosphates under copper catalysis. The resulting allyl?B(dan) was convertible into 1,3-, 1,2-, or

BF3·Et2O as a metal-free catalyst for direct reductive amination of aldehydes with amines using formic acid as a reductant

Fan, Qing-Hua,Liu, Xintong,Luo, Zhenli,Pan, Yixiao,Xu, Lijin,Yang, Ji,Yao, Zhen,Zhang, Xin

supporting information, p. 5205 - 5211 (2021/07/29)

A versatile metal- and base-free direct reductive amination of aldehydes with amines using formic acid as a reductant under the catalysis of inexpensive BF3·Et2O has been developed. A wide range of primary and secondary amines and diversely substituted aldehydes are compatible with this transformation, allowing facile access to various secondary and tertiary amines in high yields with wide functional group tolerance. Moreover, the method is convenient for the late-stage functionalization of bioactive compounds and preparation of commercialized drug molecules and biologically relevant N-heterocycles. The procedure has the advantages of simple operation and workup and easy scale-up, and does not require dry conditions, an inert atmosphere or a water scavenger. Mechanistic studies reveal the involvement of imine activation by BF3and hydride transfer from formic acid.

Photochemical Decarboxylative C(sp3)-X Coupling Facilitated by Weak Interaction of N-Heterocyclic Carbene

Chen, Kun-Quan,Wang, Zhi-Xiang,Chen, Xiang-Yu

, p. 8059 - 8064 (2020/11/02)

While N-hydroxyphthalimide (NHPI) ester has emerged as a powerful reagent as an alkyl radical source for a variety of C-C bond formations, the corresponding C(sp3)-N bond formation is still in its infancy. We demonstrate herein transition-metal-free decarboxylative C(sp3)-X bond formation enabled by the photochemical activity of the NHPI ester-NaI-NHC complex, giving primary C(sp3)-(N)phth, secondary C(sp3)-I, or tertiary C(sp3)-(meta C)phth coupling products. The primary C(sp3)-(N)phth coupling offers convenient access to primary amines.

One-Pot Controlled Reduction of Conjugated Amides by Sequential Double Hydrosilylation Catalyzed by an Iridium(III) Metallacycle

Agbossou-Niedercorn, Francine,Corre, Yann,Djukic, Jean-Pierre,Kalocsai, Dorottya,Michon, Christophe,Nagyházi, Márton,Rysak, Vincent,Trivelli, Xavier

supporting information, p. 6212 - 6220 (2020/10/02)

A single and accessible cationic iridiumIII metallacycle effectively catalyzes the one-pot sequential double hydrosilylation of challenging α,β-unsaturated secondary and tertiary amides to afford, in a controlled and straightforward way, the co

The electronic and steric effects of neutral and ionic phosphines on Ir(I)-complex catalyzed hydroaminomethylation of olefins

Liu, Huan,Yang, Da,Yao, Yixuan,Xu, Yongqiang,Shang, Hongyan,Lin, Xufeng

, (2020/02/26)

The electronic and steric effects of a series of neutral and ionic (mono-/di-)phosphines on the performance of Ir(I)-complex catalysts for the hydroaminomethylation of olefins were systematically investigated by means of 1J31P-7

B(C6F5)3-Catalyzed Deoxygenative Reduction of Amides to Amines with Ammonia Borane

Pan, Yixiao,Luo, Zhenli,Han, Jiahong,Xu, Xin,Chen, Changjun,Zhao, Haoqiang,Xu, Lijin,Fan, Qinghua,Xiao, Jianliang

supporting information, p. 2301 - 2308 (2019/01/30)

The first B(C6F5)3-catalyzed deoxygenative reduction of amides into the corresponding amines with readily accessible and stable ammonia borane (AB) as a reducing agent under mild reaction conditions is reported. This metal-free protocol provides facile access to a wide range of structurally diverse amine products in good to excellent yields, and various functional groups including those that are reduction-sensitive were well tolerated. This new method is also applicable to chiral amide substrates without erosion of the enantiomeric purity. The role of BF3 ? OEt2 co-catalyst in this reaction is to activate the amide carbonyl group via the in situ formation of an amide-boron adduct. (Figure presented.).

Ru-Catalyzed Deoxygenative Transfer Hydrogenation of Amides to Amines with Formic Acid/Triethylamine

Pan, Yixiao,Luo, Zhenli,Xu, Xin,Zhao, Haoqiang,Han, Jiahong,Xu, Lijin,Fan, Qinghua,Xiao, Jianliang

supporting information, p. 3800 - 3806 (2019/07/12)

A ruthenium(II)-catalyzed deoxygenative transfer hydrogenation of amides to amines using HCO2H/NEt3 as the reducing agent is reported for the first time. The catalyst system consisting of [Ru(2-methylallyl)2(COD)], 1,1,1-tris(diphenylphosphinomethyl) ethane (triphos) and Bis(trifluoromethane sulfonimide) (HNTf2) performed well for deoxygenative reduction of various secondary and tertiary amides into the corresponding amines in high yields with excellent selectivities, and exhibits high tolerance toward functional groups including those that are reduction-sensitive. The choice of hydrogen source and acid co-catalyst is critical for catalysis. Mechanistic studies suggest that the reductive amination of the in situ generated alcohol and amine via borrowing hydrogen is the dominant pathway. (Figure presented.).

2-Aminoquinazolin-4(3H)-one as an Organocatalyst for the Synthesis of Tertiary Amines

Thakur, Maheshwar S.,Nayal, Onkar S.,Upadhyay, Rahul,Kumar, Neeraj,Maurya, Sushil K.

supporting information, p. 1359 - 1362 (2018/03/09)

The potential of 2-aminoquinazolin-4(3H)-one as an organocatalyst for the activation of aldehydes via noncovalent interaction for the synthesis of tertiary amines using formic acid as a reducing agent is reported for the first time. The developed protocol demonstrated a dilated substrate scope for aromatic and aliphatic amines with aromatic and aliphatic aldehydes. Furthermore, the current method was also fruitful for the derivatization of ciprofloxacin and its derivative in good to excellent yields.

An efficient and recyclable ionic diphosphine-based Ir-catalyst for hydroaminomethylation of olefins with H2O as the hydrogen source

Liu, Huan,Yang, Da,Wang, Dong-Liang,Wang, Peng,Lu, Yong,Giang, Vo-Thanh,Liu, Ye

supporting information, p. 7979 - 7982 (2018/07/25)

Hydroaminomethylation of olefins with H2O as the hydrogen source was accomplished over an Ir-catalyst with the involvement of an ionic diphosphine (L6). The use of H2O as the hydrogen source could completely inhibit the hydrogenation
