摘要

Abstract 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 ...
