Summary on Grant Application Form |
Peyssonol A and B, isolated from the Red Sea alga Peyssonnelia sp., are potent inhibitors of HIV reverse transcriptases. Their structures were determined by NMR studies but, due to limited bio-availability, an unequivocal assignment of the stereogenic centres in peyssonol B could not be established.The programme seeks to effect the total synthesis of both targets. Key steps envisioned for constructing the carbocyclic framework of peyssonol A in a stereo-controlled manner include a Michael initiated anion oxy-Cope rearrangement and a stepwise intramolecular Heck - conjugate addition sequence.At this juncture a trans-diaxial ring opening of an epoxide will be used to install the axial bromine in peyssonol A and the biomimetric skeletal rearrangement studied. The tow syntheses will be completed, allowing us to comment on the stereochemistry and biosynthesis of peyssonol B.
