Significance

A synthetic procedure for the preparation of β-(hydroxymethylaryl/alkyl)-α-methylene-γ-butyrolactones is reported. In the presence of zinc or a chromium(II) source, the readily available 3-(bromomethyl)furan-2(5H)-one reacts with an aldehyde to give the title compounds in good yields and high diastereoselectivities.
