A simple, highly efficient, and sustainable strategy for the synthesis of benzoxazole and benzothiazole derivatives was developed by using inexpensive, green, readily available, and recyclable mesoporous poly(melamine-formaldehyde) as a green, heterogeneous organocatalyst. The corresponding substituted benzoxazoles and benzothiazoles were obtained in good to excellent yields by aerobic oxidation of o-substituted aminobenzenes with various aldehydes under dioxygen atm. The catalyst can be completely recovered through simple filtration to be reused more than six times without significant loss of catalytic activity. In the experiment, the researchers used many compounds, for example, 2-(3-Bromophenyl)benzo[d]oxazole (cas: 99586-31-9SDS of cas: 99586-31-9).
2-(3-Bromophenyl)benzo[d]oxazole (cas: 99586-31-9) belongs to benzoxazole derivatives. Benzoxazole derivatives have different biological activities. Benzoxazoles are prominent in medicinal chemistry due to their wide spectrum of pharmacological activities such as anti-inflammatory, antimycobacterial, antihistamine.SDS of cas: 99586-31-9
