The reaction of silicon substituted vinyloxiranes in the presence of catalytic amount of palladium (0) catalyst affords the title compounds. This new reaction proceeds smoothly, under very mild conditions and with complete chirality transfer. One-pot addition of selected organometallic nucleophiles to these aldehydes at very low temperature led to a highly selective preparation of the corresponding
硅取代的乙烯基氧杂环戊烷在催化量的钯(0)催化剂存在下的反应得到标题化合物。该新反应在非常温和的条件下顺利进行,并具有完全的手性转移。在非常低的温度下一锅法地将选择的有机金属亲核试剂添加到这些醛中导致以非常高的收率高度选择性地制备相应的醇。已经研究了取代基对硅原子和钯的配体的影响。
