Abstract
2-Arylamino-3-chloro-5,8-dihydroxy-1,4-naphthoquinones reacted with acetic anhydride and benzoyl chloride in pyridine to give in succession the corresponding O-acyl derivatives at both hydroxy groups. The primary acylation products were 8-acyloxy-2-arylamino-3-chloro-5-hydroxy-1,4-naphthoquinones.
