Abstract:

The reaction of 2-methyl-3-hydroxy-4H-pyrane-4-one (maltol) with dialkyl acetylenedicarboxylates in the presence of triphenylphosphine in CH2Cl2 at room temperature leads to the unknown fused furan and cyclobutene derivatives, and functionalized olefins in fairly high yields.

Keywords: Acetylenic esters, OH-acid, regioselective synthesis, triphenylphosphine, functionalized olefins, dihydrofurans
