Abstract
Face selectivity in Diels-Alder reactions of the semicyclic dienes (1a
) and (1b) with maleic anhydride (MA) and N-phenylmaleimide (NPM) was
examined. Cycloaddition reaction of 1 with MA occurred preferentially
from the diene face anti to the allylic hydroxy group, on the other ha
nd, the cycloaddition with NPM occurred preferentially from the syn to
the hydroxy group.
