Abstract
Investigations concerning the alkaline cleavage of (+)-isoxazolo[4,5-b]usnic acid (8) are described. During these studies a novel rearrangement from the 'normal' (usnic acid) to the 'iso' (isousnic) series was revealed. The rearrangement process was then utilized in the synthesis of (+)-isousnic acid (3).This publication has 1 reference indexed in Scilit:
