The regioselectivity of the Diels-Alder reaction between ω-substituted dienoates and unsymmetrical dienophiles can be strictly controlled by "calixarene-like" metal complexes of type A (see scheme). The reaction of the dienoate coligand in A with acrylonitrile leads to the exclusive formation of the regioisomer adduct I, which is in striking contrast to the low regioselectivity of the background reaction. (Chemical Equation Presented).
