Tweaking mechanosensors. Both were important. Once this conformation is achieved, zirconocene-mediated cyclization of Structure 5 can occur, and oxidizing the resulting hydroxy group with TPAP will yield Structure 6. Ryckbosch, Paul A.

Ryckbosch, Paul A. Indeed the first member of this large triad of natural products families was not synthesized until many years later By reducing the ketone of Structure 1 followed by oxidizing the furan nucleus with m-CPBA and converting the resulting hydroxy group to an oxyacetate, Structure 2 can be obtained. Several steps of synthesis are required to form Structure 5 from Structure 4, with the main goal of positioning the allylic branch of the seven-membered ring in a trans conformation.

More complex and more biologically important tiglianes, daphnanes and ingenanes had not been synthetically approached. Indeed the first member of this large triad of natural products families was not synthesized until many years later Structure 6 contains all three rings of the RTX backbone and can then be converted to resiniferatoxin through additional synthesis steps attaching the required functional groups. Long V. At the outset, I wish to acknowledge the many mentors, students, colleagues, family and friends who have figured and continue to figure in this journey.

In fact, the first syntheses of pseudoguaianes, 11 5—7 ring systems with interesting biological activities, appeared only in Wender, J. By reducing the ketone of Structure 1 followed by oxidizing the furan nucleus with m-CPBA and converting the resulting hydroxy group to an oxyacetate, Structure 2 can be obtained.
