Microwave-assisted Synthesis of 2-Substituted Naphtho[1,2-d][1,3]oxazoles by Reacting 1-Nitroso-2-naphthol with Allyl Bromides and Benzyl Bromides using FeCl3 as Catalyst

Abstract

Efficient and improved preparation of 2-substituted[1,2-d][1,3]oxazoles by the reaction of 1-nitroso-2-naphthol and allyl bromides, benzyl bromides under microwave condition utilizing FeCl3 as a catalyst with yield ranging from 32% to 72%. Reaction with bromo acetonitrile yields the corresponding 2-cyanonaphthoxazole with 58% yield.
