63139-23-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 63139-23-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,1,3 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 63139-23:
(7*6)+(6*3)+(5*1)+(4*3)+(3*9)+(2*2)+(1*3)=111
111 % 10 = 1
So 63139-23-1 is a valid CAS Registry Number.

Anti-carbometalation of alkynyl sulfides using indium tribromide and ketene silyl acetals

Kang, Kyoungmin,Nishimoto, Yoshihiro,Sakamoto, Kosuke,Yasuda, Makoto

supporting information, p. 1136 - 1139 (2020/10/06)

We developed the regioselective anti-carbometalation of alkynyl sulfides via the use of InBr3 and organosilicon nucleophiles to give β-mercaptoalkenylindium compounds. The structure of β-mercaptoalkenylindium was characterized by X-ray crystallographic analysis. A variety of disubstituted alkenyl sulfides were regio- and stereoselectively obtained by either halogenation or Pd-catalyzed cross-coupling with aryl halides using the mercaptoalkenylindiums.

A Short Synthesis of (+)-Brefeldin C through Enantioselective Radical Hydroalkynylation

Gn?gi, Lars,Martz, Severin Vital,Meyer, Daniel,Sch?rer, Robin Marc,Renaud, Philippe

supporting information, p. 11646 - 11649 (2019/08/30)

A very concise total synthesis of (+)-brefeldin C starting from 2-furanylcyclopentene is described. This approach is based on an unprecedented enantioselective radical hydroalkynylation process to introduce the two cyclopentane stereocenters in a single step. The use of a furan substituent allows a high trans diastereoselectivity to be achieved during the radical process and it contains the four carbon atoms C1–C4 of the natural product in an oxidation state closely related to the one of the target molecule. The eight-step synthesis requires six product purifications and it provides (+)-brefeldin C in 18 % overall yield.

Synthesis of aryl α,α-difluoroethyl thioethers a novel structure motif in organic chemistry, and extending to aryl α,α-difluoro oxyethers

Tomita, Ren,Al-Maharik, Nawaf,Rodil, Andrea,Bühl, Michael,O'Hagan, David

supporting information, p. 1113 - 1117 (2018/02/22)

A method for the preparation of aryl α,α-difluoroethyl thioethers (ArSCF2CH3) is reported and the synthesis approach is extended to aryl α,α-difluoroethyl oxygen ethers. Selected building blocks are further elaborated in cross-coupli

Divergent Reactivity of Thioalkynes in Lewis Acid Catalyzed Annulations with Donor–Acceptor Cyclopropanes

Racine, Sophie,Hegedüs, Bence,Scopelliti, Rosario,Waser, Jér?me

supporting information, p. 11997 - 12001 (2016/08/16)

Efficient methods for the convergent synthesis of (poly)cyclic scaffolds are urgently needed in synthetic and medicinal chemistry. Herein, we describe new annulation reactions of thioalkynes with phthalimide-substituted donor–acceptor cyclopropanes, which gave access to highly substituted cyclopentenes and polycyclic ring systems. With silyl-thioalkynes, the Lewis acid catalyzed [3+2] annulation reaction with donor–acceptor cyclopropanes took place to afford 1-thio-cyclopenten-3-amines. On the other hand, an unprecedented polycyclic compound was formed with alkyl-thioalkynes through a reaction pathway directly involving the phthalimide group. The two transformations proceeded in good yields and tolerated a large variety of functional groups.

Facile 1,1-carboboration reactions of acetylenic thioethers

Eller, Christina,Kehr, Gerald,Daniliuc, Constantin G.,Froehlich, Roland,Erker, Gerhard

supporting information, p. 384 - 386 (2013/03/14)

The acetylenic thioether PhSCi - CSPh undergoes a rapid 1,1-carboboration reaction with facile -SPh migration upon treatment with B(C6F5)3 to yield the borylated ketene dithioacetal product (PhS)2C=C(C6/su

Sulfur-substituted tetrahedranes

Ochiai, Tatsumi,Nakamoto, Masaaki,Inagaki, Yusuke,Sekiguchi, Akira

, p. 11504 - 11507 (2011/10/04)

The stable sulfur-substituted tetrahedrane derivatives 2-4 were synthesized by the reaction of tris(trimethylsilyl)tetrahedranyllithium 1 with diphenyl disulfide, bis(4-nitrophenyl) disulfide, and bis(2,4-dinitrophenyl) disulfide, respectively, and characterized by both NMR spectroscopy and X-ray crystallography. Phenylsulfonyltetrahedrane 5 was prepared by the reaction of 2 and m-chloroperbenzoic acid. The UV-vis absorption spectra of 2-4 suggested an interaction of the σ orbital of the tetrahedrane core and the lone-pair electrons on the sulfur atom, whereas no interaction for 5 was found. Thermal reactions of 2 and 5 are also reported; 2 underwent fragmentation into two acetylene molecules, whereas 5 gave the corresponding cyclobutadiene.

Regiocontrolled synthesis of ring-fused thieno[2,3-c]pyrazoles through 1,3-dipolar cycloaddition of nitrile imines with sulfur-based acetylenes

Chandanshive, Jay Zumbar,Bonini, Bianca Flavia,Gentili, Denis,Fochi, Mariafrancesca,Bernardi, Luca,Franchini, Mauro Comes

experimental part, p. 6440 - 6447 (2011/01/13)

1,3-Dipolar cycloadditions of C-carboxymethyl-N-arylnitrile imines with substituted acetylenes bearing thiol or sulfone groups were studied. The sulfur controls the regiochemistry of the reaction, and this protocol was applied to the synthesis of ring-fus

Oxidative addition of Pd(0) to Ar-SO2R bonds: Heck-type reactions of sulfones

Homolytic carbostannylation of alkenes and alkynes with tributylstannyl enolates

Miura, Katsukiyo,Saito, Hiroshi,Fujisawa, Naoki,Wang, Di,Nishikori, Hisashi,Hosomi, Akira

, p. 4055 - 4057 (2007/10/03)

matrix presented In the presence of AIBN, tributylstannyl enolates derived from aromatic ketones reacted with electron-deficient alkenes and a variety of alkynes to give the corresponding carbostannylated adducts. The reactions with methyl acrylate gave α-tributylstannylmethyl-γ-ketoesters, unlike the known Michael-type reaction of stannyl enolates forming δ-ketoesters. The carbostannylation of alkynes proceeded in an anti addition mode to afford β,γ-unsaturated ketones. The reactivity of stannyl enolates as radical transfer agents could be utilized for radical cyclization of 1,6-enynes.
