New routes to fused isoquinolines

Treatment of 6,7-diethoxy-3,4-dihydroisoquinoline (8) and its 1-methyl derivative 12 with hydrazonoyl halides 10 in the presence of Et3N in THF under reflux afforded the corresponding 5,6-dihydro-1,2,4-triazolo[3,4-a]isoquinolines 11 and 13, re

Reaction of nitrilimines with alkoxycarbonyl-hydrazines: Synthesis of 6-acetyl-4-aryl-2-ethoxycarbonyl-1,2,3,4-tetrahydro-s-tetrazines

Nitrilimines 2 are found to react with alkoxycarbonylhydrazines 3-5 to afford the acyclic adducts 6-8. 6c is oxidized upon heating with charcoal in refluxing toluene to the corresponding formazan 9c. Compounds 8 cyclize upon heating with charcoal in reflu
