A general and efficient direct method for the α-substitution of Morita-Baylis-Hillman alcohols with carbon- and heteroatom-centred nucleophiles such as alcohols, arenes, 1,3-dicarbonyl compounds, and thiols in the presence of FeCl3·6H2O as catalyst has been developed. The reaction is operationally straightforward, accomplished in good to excellent product yields (40â99%) and with exclusive α-regioselectivity under mild conditions that did not need an inert and moisture-free environment.
