A stereoselective total synthesis of the cytotoxic natural products tubulysin U, tubulysin V, and its unnatural epimer epi-tubulysin V, is reported. A series of simplified analogs containing N,N-dimethyl-D-alanine as a replacement for the N-terminal N-Me-pipecolinic acid residue of the tubulysins is also disclosed. Biological evaluation of these natural products and analogs provided key information with regard to structural and stereochemical requirements for anti-proliferative activity and tubulin polymerization inhibition.
