Deskripsi
A concise, metal-free protocol has been established for the preparation of 2-arylbenzoxazoles from 2-nitrophenols and arylacetic acids via a sulfur-mediated redox decarboxylative cyclization reaction. The reactions proceeded in moderate to good yields, and gram-scale is suitable. Keywords: Benzoxazoles, Arylacetic acid, Decarboxylation, Cyclization, Elemental sulfur
