variety of carbonyl compounds such as aldehydes, ketones, acyloins and α-diketones to their corresponding alcohols in high to excellent yields. Reduction reactions were carried out in wet THF at r. t. In addition, regioselective 1,2-reduction of α,β - unsaturated aldehydes and ketones was achieved perfectly with this reducing system. By decreasing the amount of aprotic solvent, all reductions took place
NaBH4/C(木炭)系统可将各种羰基化合物(例如醛、酮、酰基和 α-二酮)还原为相应的醇,收率非常高。还原反应在室温下在湿 THF 中进行。此外,使用该还原系统完美地实现了 α,β-不饱和醛和酮的区域选择性 1,2-还原。通过减少非质子溶剂的量,所有的减少都在固体凝胶条件下快速有效地发生
