A general and highly enantioselective arylation of carbamates derived from primary alcohols was developed by combining Hoppe's sparteine-mediated asymmetric lithiation with Negishi cross-coupling. Coupled with Aggarwal's lithiation-borylation sequence, the current method provides a short and divergent access to a variety of enantioenriched secondary and tertiary benzylic alcohols.

Page/Page column 45; 46, (2015/12/17)
A process for the stereoselective preparation of a chiral alcohol or a chiral amine, the process comprising reacting a first prochiral reactant selected from the group consisting of a ketone, an aldehyde, and an inline, with a second reactant comprising a Grignard reagent, in the presence of a chiral trans-diamim of formula (1) as defined herein. Also provided is the use of the chiral trans-diamine of formula (1) in a Grignard reaction and the chiral trans-diamines per se.
