| Abstract: | Condensation of o-aminophenol with furoyl and thenoyl chlorides in 1-methylpyrrolidin-2-one gave, respectively, 2-(2-furyl)- and 2-(2-thienyl)-1,3-benzoxazoles
in which the furan and thiophene rings showed no acidophobic properties. Reactions of 2-(2-furyl)- and 2-(2-thienyl)-1,3-benzoxazoles
with electrophilic reagents (acylation, bromination, nitration, and sulfonation) afforded products of hydrogen replacement
in both hetaryl and benzene rings, depending on the conditions. |
