An efficient indium-mediated 2-bromoallylation of aldehydes at low temperature in aqueous DMF
摘要:
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.
