The kinetic hydroboration of allenylsilane 5 with (dIpc)2BH at -40°C provides allylborane 9Z with >12:1 selectivity. When the hydroboration is performed at temperatures above -40°C, 9Z isomerizes to the thermodynamically more stable allylborane 9E with>20:1 selectivity. Subsequent treatment of 9Z or 9E with aldehydes at -78°C provides syn- or anti-a-hydroxyallylsilanes, 7 or 8, respectively
Stereoselective synthesis of γ-substituted (Z)-allylic boranes via kinetically controlled hydroboration of allenes with 10-TMS-9-borabicyclo[3.3.2] decane

(Chemical Equation Presented) Kinetically controlled hydroboration of allenes 8 and 14a-d with the readily accessible Soderquist borane 7, which is generated in situ from borohydride 6, constitutes a convenient and preparatively useful method for synthesi
