119267-77-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 119267-77-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,2,6 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 119267-77:
(8*1)+(7*1)+(6*9)+(5*2)+(4*6)+(3*7)+(2*7)+(1*7)=145
145 % 10 = 5
So 119267-77-5 is a valid CAS Registry Number.

Br?nsted-base-catalyzed remote cascade reactivity of 2,4-dienones-asymmetric synthesis of tetrahydrothiophenes

Przydacz, Artur,Kowalczyk, Rafa?,Albrecht, ?ukasz

, p. 9566 - 9569 (2017)

This study demonstrates that the remote cascade functionalization of 2,4-dienones can be realized by employing Br?nsted base catalysis. The developed cascade involving 1,6-addition followed by the intramolecular aldol reaction provides a straightforward a

Intermolecular Phosphite-Mediated Radical Desulfurative Alkene Alkylation Using Thiols

Lopp, John M.,Schmidt, Valerie A.

supporting information, p. 8031 - 8036 (2019/10/19)

We report herein the development of a S atom transfer process using triethyl phosphite as the S atom acceptor that allows thiols to serve as precursors of C-centered radicals. A range of functionalized and electronically unbiased alkenes including those containing common heteroatom-based functional groups readily participate in this reductive coupling. This process is driven by the exchange of relatively weak S-H and C-S bonds of aliphatic thiols for C-H, C-C, and S-P bonds of the products formed.

Synthesis of 2-Aminoazoles from Thioesters via α-Heterosubstituted Ketones by Copper-Mediated Cross-Coupling

Kobayashi, Hiroyuki,Eickhoff, John A.,Zakarian, Armen

, p. 9989 - 9999 (2015/11/03)

Facile synthesis of a variety of α-heterosubstituted ketones under mild conditions was achieved by copper-mediated cross-coupling of thioesters with functionalized organostannanes. Application of this coupling methodology provided a concise pathway for the conversion of carboxylic acids to 2-aminoimidazoles, 2-aminothiazoles, and 2-aminooxazoles via thioesters in practical yields.
