The asymmetricsynthesis of trifluoromethylated propargylic ethers and amines is described. The reaction proceeds with high enantioselectivity using a simple chiral CuI-BOX system and tolerates a broad range of alcohol, aniline and alkyne substitution. With chiralalcohols, a high diastereoselectivity is observed, indicating good catalyst stereocontrol.
描述了三氟甲基化炔丙醚和胺的不对称合成。该反应使用简单的手性 Cu I -BOX 系统以高对映选择性进行,并耐受广泛的醇、苯胺和炔取代。对于手性醇,观察到高非对映选择性,表明催化剂立体控制良好。
