Total synthesis of the originally proposed and revised structures of palmerolide A and isomers thereof

Palmerolide A is a recently disclosed marine natural product possessing striking biological properties, including potent and selective activity against the melanoma cancer cell line UACC-62. The total syntheses of five palmerolide A stereoisomers, including the originally proposed (1) and the revised [ent-(19-epi-20-epi-1)] structures, have been accomplished. The highly convergent and flexible strategy developed for these syntheses involved the construction of key building blocks 2, 19-epi-2, 20-epi-2, ent-2, 3, ent-3, 4, and enf-4, and their assembly and elaboration to the target compounds. For the union of the building blocks, the Stille coupling reaction, Yamaguchi esterification, Horner-Wadsworth-Emmons olefination, and ring-closing metathesis reaction were employed, the latter being crucial for the stereoselective formation of the macrocycle of the palmerolide structure. The Horner-Wadsworth-Emmons olefination and the Yamaguchi lactonization were also investigated and found successful as a means to construct the palmerolide macrocycle. The syntheses were completed by attachment of the enamide moiety through a copper-catalyzed coupling process.

Stereoselective syntheses of (+)-rhopaloic acid A and (-)-ent- and (¡À)-rac-rhopaloic acid A

Rhopaloic acid A (+)-1 and the related compounds (-)-ent-1 and (¡À)-rac-1 have been stereoselectively synthesized. The synthetic strategy consists of successive homologation of (2E,6E)-farnesol 7 and cyclization to form a tetrahydropyran ring, together with final introduction of an alpha-methylene group on the carboxylic moiety. The cyclization is carried out by intramolecular hetero-Michael addition leading to 2,5-disubstituted tetrahydropyrans. The stereochemistry can be rationalized by invoking a model of a chair-like transition state. The asymmetric synthesis is achieved by way of the Evans’ asymmetric alkylation procedure using (S)- or (R)-4-benzyloxazolidin-2-one as the chiral auxiliary. In the event, the configuration of natural rhopaloic acid A (+)-1 could be assigned as 2R,5S by comparison of the specific rotations of synthetic compounds with that of the natural product.

Synthesis of a Diels-Alder precursor for the Elisabethin A skeleton

A synthesis of a precursor 2 for the Elisabethin A skeleton is reported. Containing a masked quinone and a (E,Z)-diene sub-unit, it has the required elements for the envisaged intramolecular Diels-Alder reaction to form the tricyclic system of Elisabethin A. Starting from methylresorcinol, the sequence involves the preparation of an arylacetic acid, which was alpha-alkylated by a chiral building block. Subsequent HWE reaction and cis-selective Wittig olefination furnished the diene with the desired geometry.

Carbocyclic 4?-epi-formycin

Formycin is a naturally occurring biologically responsive C-nucleoside. In pursuing the design and syntheses of novel C-nucleosides, convenient access to carbocyclic C-nucleosides based on the formycin framework was a goal. One such target was carbocyclic 4?-epi-formycin (4). This compound is reported via a procedure based on an asymmetric aldol/ring closure metathesis strategy. To provide a preliminary glimpse into the biological characterization of 4 an antiviral assay was conducted. Target 4 was found to be inactive and to lack cytotoxicity to the host cells.
