Abstract
(RS)-3-(2-Chloroethyl)-beta-sultam (6) is obtained from methyl 4-bromo crotonate (1) by a five step synthesis. The analogous (R)-3-chlorometh yl-beta-sultam (12) is available from (R)-benzylcysteinol (9). While t he chlorine in 6 is replaced easily by iodine yielding 7, the analogou s reaction with 12 fails. The 3-(hydroxyethyl/methyl) substituted beta -sultams 17 and 21 are prepared by similar routes. All structures are established by spectroscopic
