and of diverse Lewis acids on the asymmetric induction of the hydroboration of acetophenone has been studied. None of the solvents used could surpass lactic acid methyl ester, and for the Lewis acids, ZnCl2 and ZnI2 showed positive effects on the enantiomeric excess (ee) and the conversion. Also, the effect of the substrate structure was investigated by comparing the conversion and ee of eight different
研究了手性溶剂和各种路易斯酸的系统变化对苯乙酮硼氢化不对称诱导的影响。所用溶剂中没有一种能超过乳酸甲酯,对于路易斯酸,ZnCl2 和 ZnI2 对对映体过量 (ee) 和转化率有积极影响。此外,通过比较八种不同酮的转化率和ee,研究了底物结构的影响。显然,芳香酮可实现的不对称诱导更高。
