A simple two-step synthesis of 4-methoxycarbonyl-2(5H)-furanone consisting of formylation of dimethyl 2-(bromomethyl) fumarate, followed by acid catalysed transesterification in methanol was carried out. It led to the corresponding substituted furanone in 67% global yield.

The first original and simple route to 3-substituted 2-cyano allylic alcohols with very good yields is described. The epoxide function in the key step acts as a protecting group during the synthesis of these allylic alcohols.
