✦ Synopsis
The sense and level of 1,2-asymmetric induction have been evaluated in the BF3.OEI ~ promoted addition of (E)crotylsilanes (R)-I and (S)-I to or-amino aldehydes 2a through 2d. The sense of carbonyl diastereoface selectivity was shown to be dependent of the chirality of the silane reagent.

## Abstract An easily available and efficient chiral __N__,__N__′‐dioxide–nickel(II) complex catalyst has been developed for the direct catalytic asymmetric aldol reaction of α‐isothiocyanato imide with aldehydes which produces the products in morderate to high yields (up to 98 %) with excellent di
