Abstract

2-Aminobenzoxazoles, 2-aminobenzothiazoles, and 2-aminobenzimidazoles are privileged heteroaromatic scaffolds in biologically active compounds and natural products (Figure 1). For example, the core scaffold of the selective inhibitor of the human P2Y1 receptor I [1] and the drug for treating insomnia II [2] is 2-aminobenzoxazole. The core structure of the anti-HIV agent III [3] and the phosphodiesterase 10 inhibitor IV [4] is 2-aminobenzothiazole. The ...
