the direct functionalization of pyridines. These reactions occur under mild conditions and exhibit broad functional group tolerance, enabling the late-stage functionalization of drug-like molecules. The reagent can be easily prepared on large scale from inexpensive reagents, and reacts in the title reaction with acetonitrile, sodiumchloride, and sodium methanesulfonate as the sole byproducts. Although

Reaction of aromatic nitrile oxides with methanesulfonyl and benzylsulfonyl chlorides in the presence of triethylamine yielded sulfonate esters of α-chloroaldoximes . Under the same reaction condit...
Trisubstituted ureas can be synthesized in a one-pot fashion from bench-stable α-chloroaldoxime O-methanesulfonates and secondary amines under mild reaction conditions.

Synthesis of imidazolidin-2-ones via the cascade reactions of α-chloroaldoxime O-methanesulfonates
4-Substituted imidazolidin-2-ones were synthesized via the one-pot reaction of bench-stable α-chloroaldoxime O-methanesulfonates and 4-aminobut-2-enoates in the presence of N,N-dimethylaminopyridine. This cascade transformation involved nucleophilic substitution, Tiemann rearrangement and intramolecular Michael addition. The electronic effect of the aryl substituent of the chloroaldoximes played a

Agricultural fungicidal compositions based on N-(sulfonyloxy)benzimidoyl halides exhibit a broad spectrum of antifungal activity, particularly against late blight, bean rust and rice blast. The synthesis of representative compounds is described, and the utility of antifungal compositions is exemplified.
