Abstract

A series of chiral Lewis bases, phosphine oxide ferrocenyl aziridinyl methanol 1-4, phosphinyl aziridinyl phosphonates 5 and 6, and phosphine oxide aziridinyl phosphonates 7 and 8 were screened for allylsilane additions to aldehydes. Among the Lewis bases, 8 was found to catalyze the reaction by forming the product in up to 94% yield and with 77% ee. (C) 2015 Elsevier Ltd. All rights reserved.
