Abstract
The results of the reaction of usnic acid (1) with hydroxylamine are presented. Four products, two isomeric isoxazoles (2 and 4), a novel oxazocine structure (3), and Δ2,11-enaminousnic acid (5) were isolated and characterized. These data clarify the earlier published results in this area.This publication has 1 reference indexed in Scilit:
