摘要
The generation of the lactam enolate derived from bicyclic lactams 2a-c, prepared from (S)-pyroglutamic acid 1a, and subsequent reaction with a range of electrophiles, is reported. Exo-diastereoselectivity is generally favoured. The deprotection of some of these adducts to give functionalised hydroxymethylpyrrolidinones is readily achieved by simple hemiaminal ether cleavage under acidic conditions.
