A detailed study on the synthesis and reactions of silylmethylcyclopropanes is reported. In their simplest form, these donor-only cyclopropanes undergo Lewis acid promoted reaction to give either cis- or trans-tetrahydrofurans, with the selectivity being reaction condition-dependant. The adducts themselves are demonstrated to be an important scaffold for structural diversification. The combination
报道了对甲硅烷基甲基环丙烷的合成和反应的详细研究。这些仅供体的环丙烷以其最简单的形式进行路易斯酸促进的反应,以生成顺式或反式四氢呋喃,其选择性取决于反应条件。加合物本身被证明是结构多样化的重要支架。还讨论了供体-受体环丙烷中甲硅烷基供体基团与新型受体基团的组合。
