An efficient aldol reaction of indole-3-carbaldehydes with ketones is described. O-TBS-protected l-threonine promoted the aldol addition of ketones to indole-3-carbaldehydes affording 3-indolylmethanols with good to excellent yields and diastereoselectivities, and excellent enantioselectivities.
描述了吲哚-3-甲醛与酮的有效醛醇缩合反应。O-TBS保护的1-苏氨酸促进了吲哚-3-甲醛中醛酮的羟醛加成,从而提供了3-吲哚基甲醇,具有良好至优异的产率和非对映选择性,以及优异的对映选择性。
