Diastereoselective Diels-Alder reactions of a novel cyclopropenyl- containing chiral auxiliary

(Chemical Equation Presented) A novel cyclopropenyl-containing 1,3-spiroaminoalcohol auxiliary has been used in a variety of asymmetric Diels-Alder reactions providing endo adducts with diastereomeric ratios ranging from 2:1 up to >99:1. In addition, unexpected regiochemistry was observed for a Diels-Alder reaction between cyclopropenyl dienophile and 4-vinyl-1,2-dihydronapthalene.
