Asymmetric Silaboration of Terminal Allenes Bearing α-Stereogenic Centers:  Stereoselection Based on “Reagent Control” Toshimichi Ohmura Michinori Suginome 10.1021/ol060666j.s001 https://acs.figshare.com/articles/journal_contribution/Asymmetric_Silaboration_of_Terminal_Allenes_Bearing_Stereogenic_Centers_Stereoselection_Based_on_Reagent_Control_/3076906 A 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 (−)-<b>2</b> and a chiral Pd/(<i>R</i>)-<b>3</b> catalyst. The chiral reagent system efficiently controlled the stereochemistry of the new stereogenic centers even in the reactions of mismatched combinations. 2006-06-08 00:00:00 chiral reagent system combination stereogenic centers
