Polycyclic High-Density Cage Compounds via Cross Metathesis

Abstract

Herein, we report synthesis of various highly functionalized caged systems suitable as high energy density materials which were assembled by utilization of an olefin cross-metathesis strategy. We observed E-selectivity 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.
