A synthetic strategy based on tandem application of double Claisenrearrangement and two-directional ring-closingmetathesis reaction as key-steps has been developed for the synthesis of various hitherto unknown tri-, tetra- and pentacyclic benzofused bisoxepin and bisoxocin derivatives.

analogous to crownethers, are described. The chirality of these systems is based, in one case, upon the plane of chirality of paracyclophane systems and, in the other two cases, upon the axis of chirality of bridged biphenyls. Two methods are described for the measurement of chiral selectivity in the formation of complexesbetween these chiral macrocyclic host molecules and chiral guest primary alkylammonium
