Abstract

I2–TBHP-catalyzed oxidative cross coupling of N-sulfonyl hydrazones with isocyanides has been realized for the synthesis of 5-aminopyrazoles through formal [4 + 1] annulation via in situ azoalkene formation. Notable features are the metal/alkyne-free strategy, C–C and C–N bond formation, atom economy, catalytic I2, broad functional group tolerance, good reaction yields, shorter time, and also applicability to one-pot methodology.

Abstract

The palladium-catalyzed reaction of acetyl oximes with isocyanides was developed for the synthesis of 2H-pyrrol-2-imines. The key steps were (i) generation of an enamido-palladium(II) species, (ii) migratory double-isocyanide insertion, and (iii) cyclization. The scope of the synthesis of some 2H-pyrrol-2-imines was extended to the synthesis 1H-pyrrole-2,3-dione/1H-benzo[g]indole-2,3-dione derivatives via acid hydrolysis in a sequential one-pot manner.
