[reaction: see text] Chiral bicyclic thioglycolate lactams may be prepared in three steps from inexpensive commercial materials. The resulting lactams may be alkylated three times, twice using basic enolization and once using reductive enolization, to form alpha-quaternary carboxylic acid derivatives
