A series of 3,4,5-trisubstituted 2(5H)-furanone derivatives was synthesized through one-pot reaction of amines, aldehydes and diethyl acetylenedicarboxylate. Silica sulfuric acid efficiently catalyzes the 3-component reaction to afford the corresponding 2(5H)-furanones in high yields. The synthesized compounds were tested against HEPG2

A soluble bisanthene derivative, 4,11-dimesitylbisanthene, has been synthesized in three steps from bianthrone. In hot toluene, this bisanthene undergoes a clean Diels-Alder reaction with diethyl acetylenedicarboxylate to give a rearomatized 1:1 cycloadduct and, more slowly, a rearomatized 2:1 cycloadduct. In
