Calculate Digit Verification of CAS Registry Number 103733-17:
(8*1)+(7*0)+(6*3)+(5*7)+(4*3)+(3*3)+(2*1)+(1*7)=91
91 % 10 = 1
So 103733-17-1 is a valid CAS Registry Number.

Enantioselective One-Pot Synthesis of β-Lactams from Achiral 2-Pyridylthioesters and Aromatic Imines

Annunziata, Rita,Benaglia, Maurizio,Cinquini, Mauro,Cozzi, Franco

, p. 613 - 616 (2007/10/02)

The enolates derived from 2-pyridylthioesters by reaction with BCl3*SMe2 and enantiomerically pure aminoalcohols react with aromatic imines in an enantioselective fashion (ee up to 78percent) to afford β-lactams in a convenient one-pot procedure.
