The three-component reaction of triphenylphosphine,dialkyl but-2-ynedioate and arylidene pivaloylacetonitrile in dry methylene dichloride at room temperature resulted in unexpected densely substituted 1-(triphenyl-λ~5-phosphanylidene)ethyl)-2,3-dihydrofurans in satisfactory yields with high diastereoselectivity.The relative configuration of the 2,3-dihydrofurans was elucidated by determination of single crystal structures.
