## Abstract __N__โ€Silylated 3โ€acetoxyโ€1,2โ€thiazetidine 1,1โ€dioxide (5) is prepared from Lโ€cystine. Reactions of 5 with silyl enol ethers yield Cโ€3โ€substituted ฮฒโ€sultams 6, 12 and 15. Desilylation of 6 affords 7, which undergoes photochemical cyclization to give the bicyclic ฮฒโ€sultam 10. In the cour
