Breaking kamp: A catalytic route toward chiral α‐alkyl‐β‐ketoesters using the title reaction of α‐alkyl diazoester with aldehydes has been developed (see scheme). The reaction proceeds with high to excellent enantioselectivities and this methodology was applied to a concise two‐step synthesis of the natural pheromone sitophilate.
破坎普:朝向用α -烷基diazoester与醛标题反应已经开发手性α-烷基-β酮酯的催化路线(参见方案)。该反应具有高至优异的对映选择性,这方法适用于天然信息素sitophilate一个简明的两步合成。
