In this article a mild, simple, safe, and chemoselective synthesis and reduction of o-quinone methides to the corresponding 3-alkyl-2-hydroxy-1,4-naphthoquinones, compounds with interesting biological activity, mediated by the formic acid-water system is described. This new one-pot methodology was applied to the synthesis of lapachol and constitutes an efficient and inexpensive alternative for the preparation of this natural bioactive compound
本文介绍了一种温和、简单、安全且化学选择性强的合成与还原邻醌甲烷为相应的3-烷基-2-羟基-1,4-萘醌的方法,这些化合物具有有趣的生物活性,通过甲酸-水体系介导。这种新的一锅法方法应用于合成拉帕醇,为制备这种天然生物活性化合物提供了一种高效且经济的替代方案。
