Indium-Promoted Chemo- and Diastereoselective Allylation of α,β-Epoxy Ketones with Potassium Allyltrifluoroborate
摘要:
A practical method for the chemo- and diastereoselective allylation of alpha,beta-epoxy ketones has been developed by using the convenient air and moisture stable reagent potassium allyltrifluoroborate. Indium metal was found to promote addition in stoichiometric or catalytic amounts, to afford alpha,beta-epoxyhomoallylic tertiary alcohols in high yields and diastereoselectivities, without competing ring-scission of the epoxide.
