Abstract
Furans have been efficiently synthesised by a three-step reaction sequence. Michael addition of keto esters to alkenyl sulfoxides followed by Pummerer rearrangement afforded the cyclic intermediates 11 in good yield. Treatment of the latter with 2-chloroperoxybenzoic acid led by oxidation and syn-elimination of the corresponding sulfoxide, to substituted furans.Keywords
