Friedel-Crafts acylation of alkenes with beta,gamma-alkenoyl halides leads to conjugated Al-trienolates able to cyclize into Al-enolates of 2-cyclohexenones through an allowed thermal disrotatory electrocyclization mechanism. Discussion of the product structure is based on two-dimensional NMR experiments (400 MHz) and molecular mechanics studies (GENMOL and MM2).
