Imines derived from aldehydes and 2-aminophenols reacted with allyltrichlorosilanes in the presence of DMF, HMPA, or pyridine N-oxide as a neutral coordinate-organocatalyst to afford the corresponding homoallylic amines in high yields with high stereoselectivity; this is the first example of allylation of imines with allyltrichlorosilanes.
来自醛和2-氨基苯酚的亚胺与烯丙基三氯硅烷在DMF、HMPA或吡啶N-氧化物作为中性配位有机催化剂的存在下反应,得到相应的同烯丙胺,产率高且立体选择性强;这是亚胺与烯丙基三氯硅烷发生烯丙基化的首次例子。
