Title: Reactions of 3‐acetyl‐2‐aminotropones and 2‐acetyl‐7‐aminotropones with hydrazine
Abstract: Abstract 3‐Acetyl‐2‐aminotropone ( 1a ) reacted with hydrazine to afford its hydrazone ( 3a ) and 3‐methyl‐1,8‐dihydrocycloheptapyrazol‐8‐one ( 4 ), while methylamino‐ and pyrrolidinyl‐substituted compounds 1b and 1c gave only the cyclized compound ( 4 ). Reactions of 2‐acetyl‐7‐aminotropones 2a‐d gave their hydrazones 5a‐d and the hydrazone 6 . The hydrazones 3a and 5b were heated in acetic acid to give 4 and 3‐methyl‐8‐methylamino‐1,2‐diazaazulene ( 7 ), respectively. Several reactions of 4 and 6 were also described.
