Calculate Digit Verification of CAS Registry Number 187144-59:
(8*1)+(7*8)+(6*7)+(5*1)+(4*4)+(3*4)+(2*5)+(1*9)=158
158 % 10 = 8
So 187144-59-8 is a valid CAS Registry Number.

Baker's Yeast Reduction of α-(Acylamino)acetophenones and Lipase Catalyzed Resolution of 2-Acylamino-1-arylethanols

Izumi, Taeko,Fukaya, Katsumi

, p. 1216 - 1221 (2007/10/02)

Enzymatic reduction of α-acylaminoacetophenones with fermenting baker's yeast afforded optically active (R)-2-acylamino-1-arylethanols.Furthermore, lipase-catalyzed resolution of the 2-acylamino-1-arylethanols using vinyl acetate as an acyl donor resulted in the formation of (S)-1-acetoxy-2-acylamino-1-arylethanols and (R)-2-acylamino-1-arylethanols.
