Abstract A general and practical one‐pot synthesis of naphthopyran derivatives using hexadecyltrimethylammonium bromide (HTMAB) as catalyst (10 mol%) is described. This method provides several advantages such as neutral conditions, high yields and simple workup procedure. The catalyst is low cost, facile, active, environmentally friendly, and reusable. In addition, water is chosen as a green solvent
摘要描述了使用十六烷基三甲基溴化铵 (HTMAB) 作为催化剂 (10 mol%) 的通用和实用的萘并吡喃衍生物的一锅法合成。这种方法提供了几个优点,例如中性条件、高产率和简单的后处理程序。该催化剂成本低、操作简便、活性高、环境友好、可重复使用。此外,选择水作为绿色溶剂。
