577974-19-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 577974-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,7,9,7 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 577974-19:
(8*5)+(7*7)+(6*7)+(5*9)+(4*7)+(3*4)+(2*1)+(1*9)=227
227 % 10 = 7
So 577974-19-7 is a valid CAS Registry Number.

Catalytic, asymmetric Mannich-type reactions of α-imino esters bearing readily removable substituents on nitrogen

Nakamura, Yoshitaka,Matsubara, Ryosuke,Kiyohara, Hiroshi,Kobayashi, Shu

, p. 2481 - 2484 (2007/10/03)

(Matrix presented) Catalytic, enantioselective Mannich-type reactions of α-imino esters bearing readily removable substituents on nitrogen are described. Several N-carbamate-protected α-imino esters, which are readily prepared from 2-bromoglycine esters using a polymer-supported amine, reacted with silicon enolates to afford the desired adducts in high yields with high enantioselectivity using a copper(II)-diamine complex. Easy deprotection of the product amine and transformation to free o-amino acid derivatives have also been demonstrated.
