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.
以 FeCl3 为催化剂,在微波条件下,1-亚硝基-2-萘酚与烯丙基溴、苄基溴反应高效、改进制备 2-取代[1,2-d][1,3]恶唑,收率范围为32% 至 72%。与溴乙腈反应生成相应的2-氰基并恶唑,产率58%。
