1,3-Dipolar cycloaddition of nitrones on several allyl silanes, allyl ethers, and allyl alcohol was investigated. The silicon atom in dipolarophiles controlled the regioselectivity in favor for 5-(silylmethyl)isoxazolidines, while the oxygen atom for 4-(alkoxymethyl)isoxazolidines.
研究了硝酮在几种烯丙基硅烷、烯丙基醚和烯丙醇上的 1,3-偶极环加成反应。亲偶极体中的硅原子控制区域选择性,有利于 5-(甲硅烷基甲基)异恶唑烷,而氧原子则控制 4-(烷氧基甲基)异恶唑烷。
