Calculate Digit Verification of CAS Registry Number 134905-67:
(8*1)+(7*3)+(6*4)+(5*9)+(4*0)+(3*5)+(2*6)+(1*7)=132
132 % 10 = 2
So 134905-67-2 is a valid CAS Registry Number.

STEREOSELECTIVE ONE-POT SYNTHESES OF TRANS-3-AMINO-β-LACTAMS FROM ZINC ENOLATES OF N-PROTECTED α-AMINOACID ESTERS AND IMINES

Steen, Fred H. van der,Jastrzebski, Johann T.B.H.,Koten, Gerard van

, p. 2467 - 2470 (2007/10/02)

A new one-pot synthesis of 3-amino-β-lactams that is based on the condensation of simple imines with zinc enolates of disilyl protected glycine esters is reported.Isolated yields are high and a trans-selectivity is observed.
