significant impact in developing countries. Due to the limited number and toxicity of current therapies, new drug leads are urgently needed. In this work, four aporphine natural products were synthesized using an enantioselective, modular and convergent strategy, comprising eight steps in the longest linear sequence; key steps included Bischler-Napieralski cyclization/Noyori asymmetric reduction to
南美锥虫病和内脏利什曼病是被忽视的原生动物疾病,在发展中国家具有重大影响。由于当前疗法的数量和毒性有限,因此迫切需要新的药物线索。在这项工作中,使用对映选择性,模块化和收敛性策略合成了四种紫花ph碱天然产物,包括最长线性序列中的八个步骤。关键步骤包括Bischler-Napieralski环化/ Noyori不对称还原以构建四氢异喹啉,以及钯催化的芳基化反应以封闭C环。Norglaucine,nordicentrine和dicentrine对T. cruzi和L. infantum表现出有希望的生物活性,这表明这些支架有可能进一步发展为抗寄生虫剂。
