Chemistry of the Pseudobasic Amino Alcohols. Part 40. Synthesis of Three New Condensed Nitrogen Heterocyclic Systems
摘要:
Replacement of the central oxygen atom of the heptacyclic condensed diisoquinoline 3 by reaction with hydrazine, hydroxylamine or thiourea in a simple method gave three new heterocyclic ring systems involving 1,2,4,5-tetrazine (7), 1,2,4,5-oxatriazine (8) and 1,2,4,6-tetrazepine (9) central rings.
