  Diazotization of Methyl 3-Amino-7-Isopropyl-2-Methoxyazulene-1-Carboxylate and its 5-Isopropyl Isomer- a Convenient Synthesis of 1,2-Azulenequinone Derivatives

  摘要：

  AbstractMethyl 3‐amino‐2‐methoxy‐7‐isopropylazulene‐l‐carboxylate(8a) and its 5‐isopropyl isomer (8b) were synthesized by reduction of the 3‐nitro derivatives (7a,b) with zinc/acetic acid in excellent yields. 7a and 7b were prepared by nitration and methylation of methyl 7‐isopropyl‐2‐hydroxyazulene‐l‐carboxylate (5a) and methyl 5‐isopropyl‐2‐hydroxyazulene‐l‐carboxylate (5b), respectively. Diazotization of 8a with sodium nitrite in trifluoroacetic acid at 0 °C gave methyl 5‐isopropyl‐1,2‐azulenequinone‐3‐carboxylate (9a) in 91% yield. Similar reaction of 8b gave the corresponding methyl 7‐isopropyl‐1,2‐azulenequinone‐3‐carboxylate (9b) in 93% yield. No evidence for the formation of l‐diazo‐1,2‐azulenequinones was obtained.
