                                    The reaction of various ethyl 3-[[2-(1-hydroxyiminoalkyl)phenyl]carbamoyl]acrylates (2) with electron deficient olefins proceeds via a sequential dipole formation, dipolar cycloaddition sequence to furnish the tetrahydroisoxazolo[2,3-d][1,4]benzodiazepin-6(5H)-ones and tetrahydroisoxazolo[4,3-c]quinolin-4(5H) (4) and (6). The product distribution reflects the nature of the reacting olefin and the position and extent of substitution on the acrylate moiety.
