Regio- and Stereoselectivity of Intramolecular Diels-Alder Reactions of Fumarates: An Unusual Rearrangement-Cyclization
Eberle, Marcel K.,Weber, Hans-Peter
, p. 231 - 235 (1988)
The fumarate esters of the three isomeric phenylhexadienols 1a-c underwent an itramolecular Diels-Alder reaction to give the single product 4a.The substituted sorbic alcohol derivatives 1d-f gave similar products 4b-e.The assigned stereochemistry of the f
Phosphine-catalyzed asymmetric formal [4+2] tandem cyclization of activated dienes with isatylidenemalononitriles: Enantioselective synthesis of multistereogenic spirocyclic oxindoles

The first highly enantioselective formal [4+2] tandem cyclizations between isatylidenemalononitriles and activated dienes catalyzed by bifunctional chiral phosphine catalysts have been developed, yielding multistereogenic spirocyclic oxindoles in high yie
