Baeyer-Villiger oxidation of 1-methylpentacyclo[5.4.0.02,6.03,10.05,9] undecane-8,11-dione, performed by using m-chloroperbenzoic acid in 1:1 molar ratio, resulted in the formation of monolactone. The corresponding dilactone, was synthesized by reacting 1-methyl-PCU-8,11-dione with m-chloroperbenzoic acid in 1:2 molar ratio. 6-Methyl-1,4,4a,8a-tetrahydro-1,4-methanonaphthalene-5,8-dione was converted into the corresponding exo-6,7-monoepoxide via treatment with 30% aqueous hydrogen peroxide. Epoxidation of this monoepoxide by using m-chloroperbenzoic acid afforded the corresponding bis-epoxide. Ceric ammonium nitrate (CAN) promoted oxidation of 1-methyl-PCU-8,11-dione afforded "methylated lactones" and a "methylated alkene."

The syntheses of the unsymmetrical 14-membered bismacrolides have been reviewed. A total synthesis of clonostachydiol, the latest to join this family, has been attempted using trimethylsilyl acetylene as the builiding block and palladium catalyzed reactions for the formation of key bonds. The alkyne groups were introduced by Stille coupling of trimethylstannylethynyltrimethylsilane with an acid chloride for one fragment and by addition of lithiotrimethylsilyl acetylene to an aldehyde for the other. Lactic acid derivatives were chosen as starting materials for both fragments, thus introducing two of the chiral centers. The remaining stereocenters were introduced using stereoselective reductions of ketones.

Plakortide E (85), which is isolated from the Jamaican marine sponge Plakortis halichondrioides, contains a five-membered peroxide ring, with the oxygen atoms are linked to tertiary C4 and C6 centers.34,57 In this thesis, the total synthesis of plakortide E (85) is described. A novel palladium-catalyzed approach towards 1,2-dioxolanes has been developed. A lipase-catalyzed kinetic resolution was employed to provide optically pure 1,2-dioxolane central cores. Coupling of the central cores and side chains was achieved by a Negishi reaction. All four isomeric structures of plakortide E methyl ester, namely, 86a-d were synthesized, and one of these molecules, 86d proved to be natural plakortide E methyl ester on the basis of 1H, 13C NMR spectra and specific rotation. With plakortide E methyl ester (4S,6R, 10R)-(-)- cis-(86d) and its other three isomers in hand, we successfully converted them into plakortone B (3S,4S,6 R,10R)-(87a), and its isomers ent-87a, 87b and ent-87b via an intramolecular oxa-Michael addition/lactonization cascade reaction. Saponification converted 1,2-dioxolane 86d into plakortide E (85a) whose absolute configuration (4S,6 R,10R) was confirmed by comparison of spectral and physical data with those previously reported.35b / Sun, Xiaoyu. / Adviser: Henry N.
