Tandem Condensation/Rearrangement Reaction of 2-Aminohetarene N-Oxides for the Synthesis of Hetaryl Carbamates
A new approach to hetaryl carbamates through a tandem condensation/rearrangement reaction of 2-aminohetarene N-oxides was developed. The developed reaction is suitable for both five- and six-membered heterocycles and proceeds through the condensation of 2

Chloroformate free, scalable approach for the synthesis of organic carbamates and their alkylation
A convenient method for the synthesis of organic carbamates of 2-aminopyridine without using hazardous chloroformate reagent is developed. This alternate approach for the synthesis of organic carbamates and their alkylation to 2-alkylaminopyridines is more practical and economical to be used on large scale. The amazing behavior of 2- aminopyridine helps in forming organic carbamates unlike 3-aminopyridine and 4-aminopyridine.
