摘要：

Condensation of 2-alkynyl-1-chloro- and 1-alkynyl-2-chloroanthraquinones with Na2S under mild conditions afforded anthra[1,2-b]thiophene-6,11-diones and anthra[2,1-b]thiophene-6,11-diones, respectively. A variety of angular anthrathiophenediones was synthesized by this method. The acetylenic precursors were prepared by a modified procedure of the Sonogashira reaction.
