Regio- and Stereo-chemical Effects in the Hydroboration ofΔ2 -Steroidal Allylic and HomoallylicAlcohols?

Journal of Chemical Research, Synopses Pub Date: DOI: 10.1039/A702014G

Abstract
A comparison between the hydroboration ofΔ 2 -steroidal 1α-allylic and5α-homoallylic alcohols reveals that whereas both have astereochemical directing effect, only the allylic alcoholmodifies the regiospecificity of the reaction.
