The reaction rate and stereoselectivity of intermolecular dipolar 1,3 cycloaddition of the C,N-dialkylnitrone to olefins with hydroxyl groups and their derivatives were found to depend upon the type of hydroxyl group. The rate is accelerated in the o

A combination of 1, 3-dipolar cycloaddition of Z-nitrones to the chiral dipolarophile and subsequent ring transformation of the resulting adducts to the piperidinols has provided a new practical synthesis of 2, 6-disubstituted 3-piperidinol alkaloids

Cycloaddition of the nitrone, derived from tetradecanal, to 2-aminobut-3-en-1-ol provides a practical asymmetric synthesis of both (2R,4R,5S)-tetrahydropseudodistomin and all the stereoisomers of racemic tetrahydropseudodistomin.
