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 features of this protocol. 相似文献

A novel and simple t‐BuOLi/I2‐mediated synthesis of 1,2,4‐trisubstituted imidazoles was developed without transition‐metal added. The transition‐metal‐free strategy tolerated a range of substrates and provided products in moderate to good yields with 100% regioselectivity. 相似文献
