The obtained molecules contained diversified functional groups, allowing their incorporation in bioactive compounds in versatile modes. Described synthetic approaches afforded multigram-scaled synthesis of the desired compounds with good yields, thus being applicable in drug designenpiperidineazetidinebioisosterpipecolic aciddrug designСтаття
