Cycloaddition Reactions with Azabenzenes, IX). - Synthesis and Structure of Cyclopenta[c]-pyrido[2.1-f][1,2,4]triazinesThe 1,2,4 triazines 1a-1g react with dimethyl 4,5,6,7-tetrachlorospiro[2.4]hepta-1,4,6-triene-1,2-dicarboxylate (4), giving cyclopenta[c]pyrido[2.1-f][1,2,4]triazines 5a-5g whose structure was determined by X-ray analysis. compounds 1g and4 give, besides 5g, an isomeric compound which is a cyclopentap[c]pyrido[2.1-b][1,2,4]triazine 12.
Notes:
Die 1,2,4-Triazine 1a-1g reagieren mit 4,5,6,7-Tetrachlorspiro[2.4]hepta-1,4,6-trien-1,2-dicarbonsäure-dimethylester (4) zu Cyclopenta[c]pyrido[2.1-f]p1,2,4]triazinen 5a-5g, deren Struktur durch Röntgenstrukturanalyse von 5a gesichert wurde. Aus 1g and 4 entstand neben wenig 5g eine isomere Verbindung, bei der es sich um ein Cyclopenta[c]pyrido[2.1-b][1,2,4]-triazin 12 handelt.
