Reduction of N-(γ-oxoacyl)oxazolidinone with a borohydride reagent, such as NaBH4 or LiBEt3H, resulted in formation of the corresponding lactone or lactol. In contrast, when an aluminum hydride reagent was used instead of a borohydride reagent, reduction of N-(γ- or δ-oxoacyl)oxazolidinone proceeded unexpectedly to give not the corresponding lactone or lactol, but a tetrahydrofuran or tetrahydropyran derivative, respectively, containing an oxazolidino group.
使用硼氢化物试剂,如NaBH4或LiBEt3H,对N-(γ-氧代酰基)噁唑烷酮进行还原,结果生成相应的内酯或半缩醛。相反,当使用铝氢化物试剂代替硼氢化物试剂时,N-(γ-或δ-氧代酰基)噁唑烷酮的还原过程出乎意料地产生不对应的内酯或半缩醛,而是分别生成了含有噁唑烷基团的四氢呋喃或四氢吡喃衍生物。
