Abstract
A variety of quinoline-4-amines were synthesized from substituted 3-(2-nitrophenyl)isoxazoles utilizing Zn or Fe dust and HOAc via a reductive heterocyclization process. The starting isoxazoles were synthesized from readily available starting materials. A brief survey of functional groups tolerated in this reductive heterocyclization was performed and several 10-amino-3,4-dihydrobenzo[b][1,6]naphthyridin-1(2H)-one and 9-amino-3,4-dihydroacridin-1(2H)-one examples were synthesized.
摘要
通过还原杂环化过程，利用锌粉或铁粉以及醋酸，从取代的3-(2-硝基苯基)异恶唑合成了多种喹啉-4-胺。起始异恶唑由易得的原料合成。对该还原杂环化过程中可耐受的官能团进行了简要研究，并合成了几个10-氨基-3,4-二氢苯并[b][1,6]萘啶-1(2H)-酮和9-氨基-3,4-二氢吖啶-1(2H)-酮的实例。
