Gan, Haifeng published the artcileFacile Preparation of Benzoxazoles from S8-Promoted Cyclization of 2-Nitrophenols with Arylmethyl Chloride, COA of Formula: C7H6Cl2, the publication is ChemistrySelect (2019), 4(9), 2858-2860, database is CAplus.
A simple, metal-free methodol. has been obtained for the preparation of 2-arylbenzoxazoles I (R = H, 6-Me, 5-NHC(O)CH3, etc.; R1 = Ph, naphthalen-2-yl, pyridin-4-yl, etc.) from 2-nitrophenols 2-NO2-R2 -C6H3OH (R = H, 5-Me, 4-F, etc.) and arylmethyl chlorides R1CH2Cl via an elemental sulfur-promoted cyclization reaction. The reactions proceeded in moderate to good yields, and gram-scale is applicable.
