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.

Acylation of O,N-acetal 1 gives excellent yields of the C-7 substituted products 2a,b.Alkylation of 2a under mild conditions gives high yields of the exo- 3 and endo- 4 substituted products in varying ratios, depending on the alkylating agent.The unsatura
