Formation of 2-cyclohexenones by Friedel-Crafts acylation of alkenes with β,γ-ethylenic acyl halides

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

Synthetic Route to Tricyclic Carbon Compounds by Friedel-Crafts Acylation

Acylation of cyclohexene by cyclohexenyl- or cyclopentenyl-acetyl chloride gave des-A-11-oxo or des-D-7-oxo steroids.
