A study of regio- and stereo-selectivity in the cycloaddition reactions of a series of symmetrical and unsymmetrical 1,2-disubstituted alkenes to the chiral, internally H-bonded N-(2-hydroxy-1-phenyl)methylenenitrone, has been carried out. The regioselectivity observed in the addition reactions is explained in terms of frontier orbital interactions. The alkenes having a hydroxymethyl substituent at the allylic position are found to undergo regio- as well as highly stereo-selective cycloaddition reactions in the presence of anhydrous magnesium bromide.
