A one pot method for chloro-dehydroxylation of carbohydrates alcohol including sterically and electrically hindered ones in excellent yield was developed. The benzotriazole-1- sulfonate proposed to play a crucial role in the reaction medium, which undergoes substitution by chloride ion in the reaction medium to give only desired chloride derivative without the formation of side product. The optimized methodology can be used in the ...
