SYNTHESIS OF BICYCLIC γ-LACTAMS VIA OXAZOLIDINONES
Baldwin, Jack E.,Lee, E.
, p. 6551 - 6554 (2007/10/02)
Oxazolidinone aldehyde 10 reacts with L-cysteine methyl ester to produce N-hydroxymethyl bicyclic γ-lactam 11 in a double cyclisation reaction.With D-cysteine methyl ester, an epimeric mixture of N-hydroxymethyl bicyclic γ-lactams 12 is obtained.Bicyclic
