Calculate Digit Verification of CAS Registry Number 140844-27:
(8*1)+(7*4)+(6*0)+(5*8)+(4*4)+(3*4)+(2*2)+(1*7)=115
115 % 10 = 5

THE STEREOCONTROLLED SYNTHESIS OF VERSATILE CARBAPENEM INTERMEDIATES USING THE BARTON O-ACYL 2-THIOPYRIDYLHYDROXAMATE FRAGMENTATION

Sumi, Kenzo,Fabio, Romani Di,Hanessian, Stephen

, p. 749 - 752 (2007/10/02)

The photo-initiated fragmentation of 2-azetidinone-4-carboxylic acid 2-thiopyridylhydroxamates (Barton reaction) in the presence of Michael acceptors leads to the introduction of a doubly functionalized carbon chain, useful for the elaboration of carbapenem and related β-lactam antibiotics.
