An efficient, inexpensive and simple method for the reduction of various α,β‐unsaturated ketones to corresponding saturated ketones using tosyl hydrazide as a hydrogen donor in DMF using calcium oxide powder has been reported. A variety of enones underwent reduction without forming undesirable side products. High chemoselectivity, broad functional group tolerance and good yields are the noteworthy
已经报道了一种有效,廉价和简单的方法,该方法使用甲苯磺酰肼作为二氧化锰在DMF中使用氧化钙粉末将各种α,β-不饱和酮还原为相应的饱和酮。各种烯酮经过还原而没有形成不希望的副产物。高化学选择性,广泛的官能团耐受性和良好的收率是该方案的值得注意的特征。
