摘要

A novel and convenient synthetic route for preparing aza-phthalimidine ydroxylactams (5a-j) by N-bromosuccinimide (NBS) was developed. This method involved the substitution reactions of substrates (3a-j) with NBS via unstable intermediate bromides (4a-j) rapidly hydrolyzed into hydroxyl products in the course of the workup process.
