Synthesis of tricyclic bridgehead olefins related to the core structure of CP-225,917 and CP-263,114—solvent, strain, and substitution effects on siloxy-Cope rearrangements
Siloxy-Cope rearrangements have been used to make bridgehead olefins, such as 15, 16b, 23b and 36—all related to the core of CP-225,917 and CP-263,114.
