Aldol reactions between N‐silylated or 2,3‐disubstituted β‐sultams and ketones or aldehydes result in the C‐4 aldol derivatives 2 and 6. Desilylation of 2 with TBAF yields the N‐unsubstituted compounds 3. Mixtures of diastereomers obtained from reactions with aldehydes are separated by CC, and their structures are elucidated by spectroscopic data.
