Abstract
Studies involving the selective O-alkylation of (+)-usnic acid [lichen] (1) have provided high yielding methods for the preparation of mono- and diether derivatives of 1. With appropriate selection of conditions, either 7- or 9-O-alkyl derivatives can be prepared.This publication has 5 references indexed in Scilit:
