  PREPARATION OF 1,7-DISUBSTITUTED-1,2,3,4-TETRAHYDROISOQUINOLINES

  摘要：

  A simple procedure for the preparation of 1,7-disubstituted-1,2,3,4-tetrahydroisoquinolines from 3,4-dihydroisoquinoline (2) is presented. This strategy overcomes the limitation of cyclisation approaches which generally require electron rich ring systems. A variety of 1-substituents has been incorporated using the appropriate organometallic or activated methylene nucleophile to prepare both electron rich (7a-f) and electron deficient 1,7-disubstituted-1,2,3,4-tetrahydroisoquinolines (16, 17).

  Development of a Scalable Synthesis of a VEGFR Inhibitor

  摘要：

  Process development and salt selection for a novel VEGFR inhibitor are described. The overall convergent synthesis involved coupling of three key fragments, 2-chloronicotinoyl chloride, 4-isopropyl-3-methylaniline and 7-aminoisoquinoline. A cost-effective and scalable synthesis of 7-aminoisoquinoline was also achieved. A transition-metal-free SNAr process enabled the final C-N coupling to afford the target molecule. A phosphate form of the drug substance with improved physical properties was selected for further development and the corresponding crystallization process was subsequently developed. Overall, a robust six-step route was developed and demonstrated on multikilogram scales affording the target compound in >30% yield and high purity (>99%).

  Graphene oxide (GO) has been developed as an inexpensive, environmental friendly, metal‐free carbocatalyst for the dehydrogenation of nitrogen heterocycles. Valuable compounds, such as quinoline, 3,4‐dihydroisoquinoline, quinazoline, and indole derivatives, have been successfully used as substrates. The investigation of various oxygen‐containing molecules with different conjugated systems indicated

  We have developed a straightforward FeCl3 promoted synthesis of dihydropyrrolo[2,1‐a]isoquinolines through formal (3+2) cycloaddition/oxidative aromatization cascade of dihydroisoquinoline with Morita‐Baylis‐Hillman carbonates (up to 96% yield). Further modifications of the obtained products were successful through simple chemical transformations providing a diverse range of natural product‐like molecules
