Diels-Alder reaction between cyclopentadiene and various dienophiles (mainly methacrolein) at -78°C was catalysed by various chiral aluminum alcoholates. The catalysts were prepared by reaction of EtAICl2 with several families of dial (or their monoether monoalcohol derivatives) . The most enantiose
