An efficient synthesis of 2-bromohomoallylic alcohols was carried out via an indium-mediated Barbier-type 2-bromoallylation of aldehydes in moderate yields. The reaction was performed at low temperature (-20 degrees C) in aqueous DMF in order to minimize decomposition of 2-bromoallylindium reagent to allene. (C) 2011 Elsevier Ltd. All rights reserved.

Bromoboration reaction of allene with boron tribromide, followed by the treatment with anisole gives (2-bromoally)diphenoxyborane which reacts with aldehydes and ketones to give 2-bromohomoallylic alcohols in excellent yields.
