Patterson, Andrew W.; Peltier, Hillary M.; Ellman, Jonathan A. published the artcile< Expedient Synthesis of N-Methyl Tubulysin Analogues with High Cytotoxicity>, Related Products of 6136-93-2, the main research area is asym synthesis methyl tubulysin analog alkylation acylation heterocyclization esterification.
An optimized and highly efficient synthesis of potent, bioactive N-Me tubulysin analogs I and II has been achieved with > 40% overall yields. This synthesis represents a significant improvement over previously reported syntheses of these and related tubulysin analogs. The stereoselective synthesis of the unnatural amino acid tubuvaline is accomplished using tert-butanesulfinamide chem. N-Alkylation to form N-Me tubuvaline is performed without protection of the tubuvaline alc. by implementing a unique N-methylation strategy via formation and reduction of a 1,3-tetrahydrooxazine heterocycle. Acylation of the hindered N-Me tubuvaline amine utilizes a novel sequence of O-acylation followed by an O- to N-acyl transfer to form the hindered amide bond between N-Me tubuvaline and isoleucine. This high-yielding synthesis should enable the production of large quantities of material for biol. studies.
