Article abstract of DOI:10.1016/S0040-4039(99)00601-2

Furans having a double bond at the α-position were obtained by phosphine-initiated cyclization of enynes bearing a carbonyl group at the ene-side in the presence of aldehyde in high yield. The reaction may involve the 1,6-addition of phosphine toward the
