Diastereofacial Controlled Addition Reaction of Alkoxymethylketones Modified by (2R,4R)-2,4-Pentanediol with Organometallics

Abstract
Oxygen functionalized chiral alkoxymethylketone, derived from (2R,4R)-2,4-pentanediol, provided an efficient chiral environment in the reaction with organometallics which resulted in the either stereoselection depending on metal used; i.e., the reactions with MeLi and MeTi(OiPr)3 selectively furnished the corresponding (S)-and (R)-tertiary alcohols, respectively.
