The Baylis-Hillman condensation of three types of α,β-conjugate cycloketones with aldehydes was successfully performed by using diethylaluminum iodide as the Lewis acid promoter alone without the direct use of a Lewis base. The reaction proceeded to completion at 0 °C in CH2Cl2 within 24 h to give modest to good yields (53â72%).

Tricyclic keto-diols have been synthesised by a three-step annulation procedure in which hydroxyenones, prepared by the coupling of 2-cyclohexen-1-one with aldehydes, are diastereoselectively epoxidised and the syn-epoxides cyclised with tin(IV) chloride. Kinetic resolution of the hydroxyenones was achieved by enantiomeric epoxidation.
