A platinum-catalyzed cycloisomerization of 1,6-enyne coupling with the rearrangement chemistry of propargylic ester has been developed. Most probably, under platinum catalysis, propargylic ester undergoes the 1,3-acyloxy migration to afford metal allene intermediate, which is followed by the Diels-Alder-type reaction. 1,3-Acyloxy migration is the key step during the transformation.
