Some reactions of nitrone 4 are described, namely the nucleophilic addition of dialkyl phosphites, HOP(OR)2, 5a–c or of diethyl methylphosphonate 8 and the dipolar [2+3] cycloaddition of vinylphosphonate 11. Chemical transformations led to 4-amino-L-fucose derivatives bearing a phosphonate group in the 1α position linked to the pyrrolidine ring through a chain of 0–2 carbon atoms. The target compounds
描述了硝酮 4 的一些反应,即亚磷酸二烷基酯、HOP(OR)2、5a-c 或甲基膦酸二乙酯 8 的亲核加成和乙烯基膦酸 11 的偶极 [2+3] 环加成。化学转化导致 4-氨基-L-岩藻糖衍生物在 1α 位带有一个膦酸酯基团,通过 0-2 个碳原子链与吡咯烷环相连。目标化合物被证明是优秀的α-L-岩藻糖苷酶抑制剂。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
