  The total synthesis of bistratamides F–I

  摘要：

  The total synthesis of bistratamides F-I (2-5) have been achieved in overall yields of 3, 10, 13, and 27%, respectively. The thiazole substructure was prepared utilizing a MnO2 oxidation of a thiazoline, synthesized from a Val-Cys dipeptide using bis(triphenyl)oxodiphosphonium trifluoromethanesulfonate. The serine-based oxazole substructure was prepared from a Val-Ser dipeptide using literature methods. The threonine-derived oxazole substructure was synthesized from a ketoamide dipeptide using the bisphosphonium salt employed for thiazoline preparation. Most of the amide bonds were formed using HBTU and HOBt in the presence of DIEA. The final macrocyclization step was accomplished efficiently by PyBOP and DMAP in all cases. (C) 2004 Elsevier Ltd.
