Abstract A six-step synthesis of the antidepressant rolipram from the popular analgetic 4-acetamidophenol (paracetamol) is described. The steps include oxidative functionalization of the aromatic core, diazonium salt formation via deacetylation-diazotation, Matsuda–Heck reaction, conjugate addition of nitromethane, and hydrogenative cyclization. A six-step synthesis of the antidepressant rolipram from
摘要 描述了从流行的止痛药4-乙酰氨基苯酚(扑热息痛)六步合成抗抑郁剂咯利普兰。这些步骤包括芳族核的氧化功能化,通过脱乙酰基-重氮化作用,重田松树-Heck反应,共轭添加硝基甲烷和氢化环化形成重氮盐。 描述了从流行的止痛药4-乙酰氨基苯酚(扑热息痛)六步合成抗抑郁剂咯利普兰。这些步骤包括芳族核的氧化功能化,通过脱乙酰基-重氮化作用,重田松树-Heck反应,共轭添加硝基甲烷和氢化环化形成重氮盐。
