Friedel-Crafts coordinated processes: highly selective synthesis of hydroxynaphthoquinones
摘要:
Simple preparation of ethyl 3-hydroxy-1,4-naphthoquinone-2-carboxylates 2 including heterocyclic analogs is accomplished by C-regioselective bis-acylation of aromatic and heteroaromatic beta-keto esters 1. Compounds 2 are readily hydrolyzed and decarboxylated to the corresponding 2-hydroxy-1,4-naphthoquinone derivatives 3.
