Silica supported fluoroboric acid: an efficient and reusable heterogeneous catalyst for facile synthesis of 2-aliphatic benzothiazoles, benzoxazoles, benzimidazoles and imidazo[4,5-b]pyridines was written by Patil, Abasaheb V.;Bandgar, Babasaheb P.;Lee, Soo-Hyoung. And the article was included in Bulletin of the Korean Chemical Society in 2010.Category: benzoxazole This article mentions the following:
2-Substituted benzothiazoles, benzoxazoles, benzimidazoles and imidazo[4,5-b]pyridines were prepared by cyclization of aminophenols, aminothiophenols, phenylenediamines and a pyridinediamine with ortho esters using silica-supported tetrafluoroboric acid a catalyst. In the experiment, the researchers used many compounds, for example, 2,5-Dimethylbenzoxazole (cas: 5676-58-4Category: benzoxazole).
2,5-Dimethylbenzoxazole (cas: 5676-58-4) belongs to benzoxazole derivatives. Benzoxazole nucleus is one of the most important heterocyclic compounds exhibiting remarkable pharmacological activities. In the past years, numerous benzoxazole derivatives have been synthesised and evaluated for their biological potential.Category: benzoxazole
