## Abstract Acylation of __N__‐silylated and 2,3‐substituted 1,2‐thiazetidine 1,1‐dioxides (β‐sultams) results in the formation of 4‐acylated β‐sultams 2 and 8. The desilylation of 2 to 3 is easily done with TBAF either on silica gel or in ethanolic solution. The acylated β‐sultams are reduced by s
