This work outlines a suitable method for the synthesis of oxepane skeleton using iterative C-glycoside technology on the oxepene intermediate, which was synthesized utilizing Wilkinson’s catalyst [Rh(PPh3)3Cl] to generate the isomerized product in a linear synthetic manner. The central core of the oxepene motif was achieved via an olefin metathesis reaction using the Grubbs second-generation and Schrock catalysts. The synthesis of the functionalized oxepane having the desired adriatoxin E-ring relative stereochemistry was achieved starting from commercially available homopropargylic alcohol.

Group A

The formation of various macrocyclic cyclophanes via ring-closing olefin metathesis is possible through the use of a pendant pentafluorobenzyl ester group. A quadrupolar interaction between the cyclophane core and the auxiliary is proposed to act as a gearing element facilitating cyclization. The development of these noncovalent interactions as gearing elements as well as the investigation of the effect of the site of metathesis upon the macrocyclization process is described.
