Solid state reductions of carbonyl groups in three cage diketones, 1a-1c, have been performed by using sodium borohydride, and the results thereby obtained have been compared with the corresponding reductions performed in ethanol solution. In each case, the solid state reduction proceeds stereospecifically; hydride transfer occurs exclusively at the face of the carbonyl group. In contrast, the corresponding
已经使用硼氢化钠对三个笼状二酮1a-1c中的羰基进行了固态还原,并将所得结果与在乙醇溶液中进行的相应还原相比较。在每种情况下,固态还原都立体定向进行。氢化物转移仅发生在羰基的表面。相反,相应的均相(溶液相)还原仅显示中等的立体选择性。
