The efficient and facilesynthesis of N-substituted furo[3,4-b]indeno[2,1-e]pyridine analogues of azapodophyllotoxin was achieved via microwave-assisted multicomponent reactions of aldehyde, 2H-indene-1,3-dione and 4-(arylamino)furan-2(5H)-one in glycol without catalyst. This method has the obvious advantages over traditional heating ones on short reaction time, high yield, operational simplicity as

Methods have been developed for the synthesis of 1,3-diazapyrenes based on the reactions of perimidines with ethoxymethylene-1,3-dicarbonyl compounds and also 6(7)-benzoyl(acetyl, formyl)perimidines with carbonyl compounds in PPA.

A method has been developed for the nitration of 6(7)-acylperimidines using sodium nitrite in formic acid. The reaction gives a mixture of 4(9)-, 9(4)-, and 7(6)-nitro-6(7)-acylperimidines from which the latter can be separated by extraction with chloroform. Reduction of the 6(7)-acyl-7(6)-nitro- perimidines yields 1H-1,5,7-triazacyclopenta[cd]phenalenes. Subsequent Schmidt reaction and reduction give 1,3,6,8-tetraazapyrenes.

Electrochemical oxidation of 6(7)-benzoylperimidines was shown to involve two stages of single electron transfer. Based on cyclic voltammetry and microelectrolysis data, a synthetic method was developed for the peri annelation of thiophene ring to benzoyl derivatives of perimidine. A new method was proposed for the preparation of 1-thia-5,7-diazacyclopenta[cd]phenalenes by fusing 6(7)-carbonyl derivatives of perimidine with elemental sulfur.
