The Reformatsky-type condensation between methyl and t-butyl 3-(N,N-dimethylamino)propionates (9) and (10) with α-alkoxy aldehydes, which has been studied on varying the protective group of the aldehyde, proceeds with good diastereoselectivity.
3-(N,N-二甲基氨基)丙酸甲酯和叔丁基酯(9)和(10)与α-烷氧基醛的Reformatsky型缩合反应已经进行了研究,该缩合反应是通过改变醛的保护基来进行的。非对映选择性。
