78956-15-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78956-15-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,5 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78956-15:
(7*7)+(6*8)+(5*9)+(4*5)+(3*6)+(2*1)+(1*5)=187
187 % 10 = 7
So 78956-15-7 is a valid CAS Registry Number.

Copper-catalyzed enantioselective carbonylation toward α-chiral secondary amides

Wu, Xiao-Feng,Yuan, Yang,Zhao, Fengqian

, p. 12676 - 12681 (2021/10/19)

Secondary amides are omnipresent structural motifs in peptides, natural products, pharmaceuticals, and agrochemicals. The copper-catalyzed enantioselective hydroaminocarbonylation of alkenes described in this study provides a direct and practical approach for the construction of α-chiral secondary amides. An electrophilic amine transfer reagent possessing a 4-(dimethylamino)benzoate group was the key to the success. This method also features broad functional group tolerance and proceeds under very mild conditions, affording a set of α-chiral secondary amides in high yields (up to 96% yield) with unprecedented levels of enantioselectivity (up to >99% ee). α,β-Unsaturated secondary amides can also be produced though the method by using alkynes as the substrate.

A novel carbonylative decomplexation of alkyne-dicobalt hexacarbonyls: Hyrocarbamoylation of alkynes

Sugihara, Takumichi,Okada, Yoshinari,Yamaguchi, Masahiko,Nishizawa, Mugio

, p. 768 - 770 (2007/10/03)

A novel carbonylative decomplexation of alkyne-dicobalt hexacarbonyls, i.e. hydrocarbamoylation of alkynes, was carried out by reaction of the complexes with 10 equiv, of primary and secondary amines.
