Asymmetric Silaboration of Terminal Allenes Bearing α-Stereogenic Centers: Stereoselection Based on “Reagent Control”
journal contribution
posted on 2006-06-08, 00:00 authored by Toshimichi Ohmura, Michinori SuginomeA highly enantioface-selective silaboration of allenes having stereogenic centers at the α-positions of the double bonds has been achieved
using a combination of a chiral silylborane (−)-2 and a chiral Pd/(R)-3 catalyst. The chiral reagent system efficiently controlled the stereochemistry
of the new stereogenic centers even in the reactions of mismatched combinations.
