Fragment A derivative (13) of nosiheptide, useful for the total synthesis, was obtained by stepwise introduction of the 2,5-bis(4-ethoxycarbonyl)-2-thiazolyl} groups and 6-(2-substituted)-4-thiazolyl} group into 3-hydroxy-5-cyanopyridine(3). The total yield was 7.6% via 14 steps.
通过逐步引入2,5-双(4-乙氧基羰基)-2-噻唑基}基团和6-(2-取代)-4 -噻唑基}基团形成3-羟基-5-氰基吡啶(3)。通过14个步骤,总产率为7.6%。
