The intramolecular 1,3-dipolar cycloaddition reactions of (Z)-N-4-alkenylni
trones carrying various alkenyl substituents were investigated, and the reg
iochemistry of the resulting isoxazolidines was determined. Silyl- and brom
o-substituents were found to effect significant regiocontrol on the intramo
lecular nitrone dipolar cycloaddition reaction. (C) 1999 Elsevier Science L
