摘要
An improved synthesis of the 7,6-fused bicyclic lactam is presented starting from readily available chiral starting materials. ( S)-allylglycine is protected as the phthalimide derivative and coupled with ( S)-2-amino-6-hydroxyhexanoic acid methyl ester. Oxidation of the hydroxyl group to the aldehyde followed by enamide synthesis and acyl iminium ion cyclization provide the bicyclic system as a single diastereomer in good overall yield.
