macrocycle is described. Key steps are mild aza-Wittig thiazole ring closures, a scandium(III)-mediated regioselective ester hydrolysis, and a highly efficient macrolactam formation with its 3-hydroxypyridine nucleus orthogonally protected. The synthesis of a 28-membered thiopeptide macrocycle is described. Key steps are mild aza-Wittig thiazole ring closures, a scandium(III)-mediated regioselective
摘要 描述了28元硫肽大环的合成。关键步骤是温和的氮杂-维蒂希噻唑环闭合,a(III)介导的区域选择性酯水解以及高效保护大环内酰胺的形成,其3-羟基吡啶核得到正交保护。 描述了28元硫肽大环的合成。关键步骤是温和的氮杂-维蒂希噻唑环闭合,a(III)介导的区域选择性酯水解以及高效保护大环内酰胺的形成,其3-羟基吡啶核得到正交保护。
