ASYMMETRIC DIELS-ALDER CYCLOADDITIONS USING CHIRAL ALKYL VINYL ETHERS AND A DIENYL SULFONE
Posner, Gary H.,Wettlaufer, David G.
, p. 667 - 670 (1986)
Chiral alkyl vinyl ethers 2b-2j underwent mild, inverse electron demand, Diels-Alder cycloadditions with 3-arenesulfonyl-2-pyrone 1 to form bridged bicyclic lactone adducts 3b-3j in excellent yields and with diastereoselectivities of up to 90percent.
