摘要
方便地合成了一种新的不对称羟醛反应的手性催化剂4(R)-(2,4,6-三甲基苄氧基)-(S)-脯氨酸.以过量的丙酮作溶剂,使用5mol%该催化剂,有效地催化了多种取代苯甲醛与丙酮间的不对称羟醛反应,产率最高达91.0%,ee最高达84.3%.
4(R)-(2,4,6-Trimethylbenzyloxy)-(S)-proline, a new chiral catalyst for the asymmetric aldol reaction, was prepared conveniently. Efficient enantioselective catalysis of aldol reactions of various benzaldehydes with neat acetone solvent was achieved with high yield (up to 91.0%) and good selectivities (up to 88.5% ee) by using 5 mol% of the catalyst.
