A Novel Type of Intramolecular Diels-Alder Reaction Involving Dienol Ethers: An Unusual Preference for a Boat Transition State in the Incipient Ring Formation

Cis and trans dienol ethers 2 and 3 have been stereospecifically synthesized and their intramolecular Diels-Alder reactions studied.While 3 did not cyclize upon prolonged heating, the cis dienol ether 2 underwent smooth cyclization through an unusual boat
