: The invention discloses a novel process for highly chemoselective reactions of substituted anilines without any detectable reaction at aromatic amino group. The invention also relates to a novel process for preparation of neostigmine methylsulphate via chemoselective reaction of 3-amionphenol and aryl dimethylcarbamates.

Facile and Efficient Synthesis of Benzoxazoles and Benzimidazoles: The Application of Hantzsch Ester 1,4-Dihydropyridines in Reductive Cyclization Reactions
Both benzoxazole and benzimidazole are common heterocyclic scaffolds in biologically active and medicinally significant compounds. Reductivecyclization of ortho-substituted nitrobenzene derivatives provides an attractive route to benzoxazole or benzimidazole ring formation. Unfortunately, only a few synthetic methods by reductivecyclization of ortho-nitro compounds have been reported and the yields
