Using an intramolecular didehydro-Diels-Alder reaction, ene-yne substituted pyrroles, thiophenes, and furans afford functionalized indoles, benzothiophenes, and benzofurans and the corresponding dihydroaromatic products. Product selectivity for the aromatic or dihydroaromatic product is controlled by the reaction conditions, which vary depending upon the substrate.

A novel method for the synthesis of 9-aryl-3a,4-dihydronaphtho[2,3-c]furan- 1(3H)-ones has been developed by P4-t-Bu-catalyzed intramolecular cascade reactions of enynes. In the presence of a catalytic amount of phosphazene P4-t-Bu base, a variety of 3-arylallyl 3-arylpropiolates underwent the cascade cyclization reaction smoothly in moderate to excellent yields.
