Borohydride Exchange Resin (BER) - nickel acetate system readily reduces nitrocinnamoylfumagillols to the corresponding amines in excellent yields, high chemoselectivity, and simple procedure. Especially, this system tolerates two epoxides (spiro-epoxide and the one on C4 alkene side chain) and the α,β-unsaturated ester moiety at C6 on the fumagillol.
硼氢化物交换树脂 (BER) - 醋酸镍系统可轻松将硝基烟酰烟碱还原为相应的胺,收率高、化学选择性高且程序简单。特别是,该系统耐受两种环氧化物(螺环氧化物和 C4 烯烃侧链上的一种)和烟曲霉醇 C6 上的 α,β-不饱和酯部分。
