The synthesis of various highly functionalized caged systems suitable as high energy
density materials, which were assembled by utilization of an olefin cross-metathesis
strategy, is reported. E-Selectivity was observed during the cross-metathesis by using Grubbs second generation
catalyst (G-II) and N-tolyl Grubbs catalyst in most of the cross-metathesis products. The stereochemistry
of the olefin formed during the cross-metathesis has been determined unambiguously
by a single-crystal X-ray diffraction study.
