Abstract

Guaiazulene, 1,4-dimethyl-7-isopropylazulene, is one of the non-benzenoid aromatic compounds consisting of fused of the seven- and the five-membered ring. Guaiazulene is an important natural product and having great potential due to its unique optical and electronic properties. In this study, a method for propargyl insertion into the C-4 methyl group of the guaiazulene is developed. A one-pot reaction of the guaiazulene, LDA, and propargyl bromide in THF affords the corresponding a new propargyl-azulene hybrid derivative. Additionally, Diels-Alder cycloaddition reaction between the propargyl-GA and tetraphenylcyclopentadienone was performed, and the cycloadduct was obtained with excellent yield. The structures of new compounds were elucidated on the basis of extensive spectroscopic (IR, NMR, and UV-vis) data analysis. This approach may be potentially useful for the development of the new azulene derivatives.
