Properties and Reactions of Substituted 1,2-Thiazetidine 1,1-Dioxides: 3-Acetoxy-1,2-thiazetidine 1,1-Dioxide, Synthesis and Reactions with C-Nucleophiles

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 course of such reacti...
