Abstract
A series of 3-aryl-substituted butenolides and butanolides has been prepared in a common short synthetic sequence from the corresponding aryl aldehydes. The 3-arylbutanolides are prepared by cyclisation of 3-aryl-3-cyano-1-propanols, obtained by selective reduction of 3-aryl-3-cyanopropionate esters, and are converted to 3-arylbutenolides by a sulfoxide or selenoxide elimination reaction.
