The Cp*RuCl-based catalyst enables expedient access to a variety of benzofused six-membered azaheterocycles from unprotected o-alkynylanilines and trimethylsilyldiazomethane through an unprecedent tandem carbene/alkyne metathesis/N-H insertion reaction. The transformation takes place under mild reaction conditions (room temperature, 15 min) and with excellent functional group tolerance. The synthetic utility of the final products and a mechanistic rationale are also discussed.

The mild and readily available Cu(NO3)2 mediated ortho nitration of anilides with broad substrate using K2S2O8 as an oxidant in the absence of any other metal catalyst and nitrating agent under mild conditions was reported for the first time.

A series of sulfonamide derivatives were synthesized by reactions with various functional groups containing benzenesulfonyl chlorides and aniline derivatives under different substitution reaction conditions. The structures of SMZ derivatives were confirmed with melting point, FT-IR, 1 H NMR, 13 C NMR, and LC-MS/MS techniques. In order to investigate the cytotoxic effects of these derivatives, we used a model plant species. The synthesized compounds (S1–S5) and sulfamethazine (SMZ) as a positive control were applied to Arabidopsis thaliana seeds. Our results indicated that S3 and S4 induced shorter roots and lower wet weight in plants. Plants treated with S2 and S5 showed no growth effects, similar to the untreated control group, while S1 slightly reduced root length and wet weight. These results suggest that S3 and the newly synthesized S4 derivatives have potential for use as herbicides since they possess cytotoxic effects on A. thaliana plants.
