Synthetic approach to oxa-triquinanes via olefin metathesis as a key step


Kotha, Sambasivarao ; Pulletikurti, Sunil


Earlier, a simple synthetic approach to cis, syn, cis-triquinanes and propellanes from exo-nadic anhydride through metathesis approach had been demonstrated. In the present work is discussed a distinct course of observations when this methodology has been extended to oxygenated exo-nadic anhydride derivatives and the importance of stereochemistry and the role of hetero atom in the outcome of olefin metathesis has been demonstrated.
