A preparative-scale synthesis of B-gamma,gamma-dimethylallyldissopinocampheylborane starting from prenyl alcohol has been described. This reagent, upon reaction with various aldehydes, provides the corresponding alpha,alpha-dimethylhomoallylic alcohols in high enantioselectivities. The application of this reagent has been demonstrated for the synthesis of C-1-C-6 Subunit of epothilone. (C) 2003 Elsevier Ltd. All rights reserved.
