## Abstract β‐Sultam‐3‐acetic acid ester 3 prepared from __rac‐S__‐benzyl‐β‐homocysteine is alkylated with bromoacetates yielding diacetates 9 which are transformed into the phenylthio esters 11. The thiazinanone derivatives 12 are obtained from 11 by rearrangement with lithium bis(trimethylsilyl)a
## Abstract __N__‐Silylated 3‐acetoxy‐1,2‐thiazetidine 1,1‐dioxide (5) is prepared from L‐cystine. Reactions of 5 with silyl enol ethers yield C‐3‐substituted β‐sultams 6, 12 and 15. Desilylation of 6 affords 7, which undergoes photochemical cyclization to give the bicyclic β‐sultam 10. In the cour
