Homochiral Matching in the Diels-Alder Clyclodimerization 2-Vinyl-7-Oxabicyclo[2.2.1]Hept-2-Ene Derivatives
-
Abstract
- Racemic 6-vinyl-7-oxabicyclo[2.2.1]hept-5-en-2-one, 5-vinyl-7-oxabicyclo[2.2.1]hept-5-en-2-one and their ethylene acetals undergo highly stereoselective Diels-Alder cyclodimerizations. The optically pure semicyclic dienes give the corresponding optically pure dimers with the same ease.
