A Rh(II)-catalyzed transannulation of N-sulfonyl-1,2,3-triazoles with 2,1-benzisoxazoles provides quinazoline derivatives. Meanwhile, a Rh(II)-catalyzed formal [3 + 2] cycloaddition of N-sulfonyl-1,2,3-triazoles with 1,2-benzisoxazoles enables a rapid synthesis of functionalized imidazole derivatives.
