A formal synthesis of (+)-lactacystin was achieved from commercially available isobutyraldehyde and ethyl acrylate. A Baylis–Hillman reaction, an intermolecular nucleophilic displacement under Mitsunobu conditions, a Sharpless asymmetric epoxidation, a palladium(0)-catalyzed syn-selective ring opening of an epoxide by treatment with an azide, a one-pot azide reductive lactamization, and a ruthenium-catayzed
(+)-lactacystin 的正式合成是由市售的异丁醛和丙烯酸乙酯实现的。Baylis-Hillman 反应、Mitsunobu 条件下的分子间亲核置换、Sharpless 不对称环氧化、钯 (0) 催化的环氧化物通过叠氮化物处理的顺式选择性开环、一锅叠氮化物还原内酰胺化和钌催化氧化被用作关键步骤。
