In the presence of CuI, 1,3-dipolar cycloadditions of N,N′-cyclic azomethine imines with iminooxindoles proceeded readily and furnished novel oxindole spiro-N,N-bicyclic heterocycles in moderate to excellent chemical yields with excellent diastereoselecti

1,3-Dipolar cycloaddition reactions are one of the most important methods to obtain diverse heterocycles with novel skeletons. We herein report the Bronsted acid or Lewis acid catalyzed [3+3] cycloaddition of azomethine imines with nonstabilized azomethine ylide generated in situ from an N-benzyl precursor, providing a clean and facile access to diverse bicyclic N-heterocycles in moderate to good yields for further biological testing. Also, the protocol developed achieved the formation of C-C and C-N bonds simultaneously in a single step.

An efficient method for the phosphine-catalyzed [3+2] cycloaddition reaction of azomethine imines with diphenylsulfonyl alkenes to give dinitrogen-fused bi- or tricyclic heterocyclic compounds in high yields has been described. Moreover, two phenylsulfony
