Exposure of γ-acyloxy butynoates to stoichiometric quantities of triphenylphosphine results in reductive condensation to afford substituted furans, by way of allenic ester intermediates. As γ-acyloxy butynoates are readily obtained through condensation of ethyl propiolate with aldehydes followed by acylation, this method represents a powerful and mechanistically novel protocol for the convergent three-component construction of substituted furans.

The directing effect of COOEt and CN groups (in position 5 in the oxazole) and CH3 group (in position 2 in the oxazole) in the Diels-Alder reactions of appropriate oxazoles with ethyl propiolate was investigated.It has been stated that CN and CH3 groups favor the formation of the ortho product and COOEt group prefers the formation of the meta product.
