本文报道了利用超声波照射可以促进NaBH~4-PEG400-THF体系对酯的还原。与用NaBH~4-PEG400体系还原酯的方法相比具有反应速度快,反应条件温和以及产物产率较高的优点,但分子内的硝基和双键不被还原,选择性较好。

The reduction of esters to alcohols with NaBH~4-PEG400-THF system promoted by ultrasond was studied. This method showed the advantages of mild reaction conditions, rapider reaction rate and higher yield. The seletivity of the method was exemplified by its inertness toward nitro group and double bond in the reduced moleculars.
