Facile Preparation of Benzoxazoles from S-8-Promoted Cyclization of 2-Nitrophenols with Arylmethyl Chloride

摘要

abstract_textpA simple, metal-free methodology has been obtained for the preparation of 2-arylbenzoxazoles from 2-nitrophenols and arylmethyl chloride via an elemental sulfur-promoted cyclization reaction. The reactions proceeded in moderate to good yields, and gram-scale is applicable./p/abstract_text
