A detailed analysis of a Lewis acid promoted ketene-alkene [2 + 2] cycloaddition is reported. The studies have led to a rationalization for an observed inversion of diastereoselectivity between thermally induced and Lewis acid promoted ketene-alkene [2 + 2] cycloadditions. The model is supported with both experimental and computational results.
报道了对路易斯酸促进的乙烯酮-烯烃[2+2]环加成反应的详细分析。这些研究为热诱导和路易斯酸促进的乙烯酮-烯烃[2+2]环加成反应中观察到的非对映选择性反转提供了合理化解释。该模型得到了实验和计算结果的支持。
