Abstract
A number of previously described aromatic bisbenzoxazoles were obtained by reductive heterocyclization. The synthesis of bisbenzoxazoles by this method made it possible to select starting compounds that are most acceptable for the synthesis of aromatic polybenzoxazoles by reductive polyheterocyclization.
