The total synthesis of (+)-papuamine, the antipode of the C(2)-symmetric, optically active, pentacyclic diamine natural product, starting from a chiraldiol is described. The diol is available via an asymmetric Diels-Alder reaction between 1,3-butadiene and di-(-)-menthyl fumarate. The keytransformation in the synthesis is an intramolecular Pd(0)-catalyzed (Stille) coupling reaction to form the central

A method of treating cancer, inflammatory disease or an infectious disease or condition in a subject in need of such treatment is disclosed. The method comprises administering to a subject an effective amount of a manzamine, or a rationally modified manzamine derivative or analog or an optical isomer or racemate or tautomer thereof or a pharmaceutically acceptable salt or prodrug thereof generated through optimized fermentation of a
