## Abstract 4‐α‐Hydroxyalkylated β‐sultams 1/5 are transformed into 4‐alkylidene‐β‐sultams 4/7 by elimination and desilylation reactions. Another route to an exocyclic double bond in the β‐sultam system has been found to be the Peterson olefination starting from 4 silylated β‐sultams 8, 10, and 11.

## Abstract The introduction of functional groups at the 4‐position of the __β__‐sultam ring was realized by the synthesis of mono‐ and disubstituted derivatives by reactions of __N__‐silylated __β__‐sultams with electrophiles in the presence of BuLi or LDA. As electrophiles, ketones, chlorosilanes
