An efficient total synthesis of the tetrahydropyran-bearing acetogenin muconin 1 is described. Palladium(0)-mediated crossed diyne coupling and the use of only D-glutamic acid as the origin of all absolute stereochemistry highlight this flexible approach thar sets the stage for access to structural analogs for further study.

A unified total synthesis is reported to access all of the possible diastereomers of pteriatoxins A-C, with the use of an intramolecular Diels-Alder reaction as the key step to form the carbo-macrocyclic core structure. The C34/C35-diol protecting groups were found to have significant effects on both the exo/endo-selectivity and the exo-facial selectivity of the intramolecular Diels-Alder process.
