A new procedure for the synthesis of β-hydroxy enones from allenyl carbinols and aldehydes is described. The use of InCl3 to promote reaction results in a mild and convenient protocol for the preparation of β-hydroxy enones.
The chemoselective reduction of an α,β-epoxyketone moiety coexisting with an enone function has been efficiently achieved with an organoselenium reagent Na+[PhSeB(OEt)3]−.
