Abstract

2-Substituted benzoxazoles (6a-j, 7a-e, 7j-l) have been synthesized via the oxidative intramolecular cyclization of Schiff's bases (4a-j, 5a-e, 5j-l) using iodobenzene diacetate (IBD) as an oxidant in dry methanol. A one-pot procedure for the synthesis of 6a-j, 7a-e and 7j-l starting from o-aminophenol/p-chloro-o-aminophenol and aldehydes has also been developed.
