SYNTHESIS OF AZULENE FROM 6-ACYLOXYFULVENES
Gupta, Y. N.,Mani, S. R.,Houk, K. N.
, p. 495 - 498 (1982)
The 6-acetoxy, tosyloxy, and p-nitrobenzoyloxy derivatives of fulvene undergo cycloadditions with 1-diethylaminobutadiene to give azulene in 12, 14, and 68percent yield, respectively.The p-nitrobenzoyloxyfulvene is a crystalline, stable substance which is highly reactive towards nucleophilic dienes.
