The results of the reduction of chiral β-enamino ketones with sodiumborohydride in aceticacid are reported. The reaction is convenient, stereoselective and high yielding and allows the preparation of enantiopure γ-amino alcohols in syn diastereoselectivity. The reaction is easy to perform and does not require expensive or hazardous chemicals. A mechanistic hypothesis is presented. The absolute configuration
报道了在乙酸中用硼氢化钠还原手性β-烯胺酮的结果。该反应方便,立体选择性和高产并允许对映体纯γ-氨基醇在制备顺式非对映选择性。该反应易于进行,不需要昂贵或有害的化学物质。提出了机械学假说。所得产物的绝对构型归因于将1 H NMR光谱数据与分子建模进行的构象分析相关联,并通过X射线分析确认。
