  Novel Series of Dihydropyridinone P2X7 Receptor Antagonists

  摘要：

  Identification of singleton P2X7 inhibitor 1 from HTS gave a pharmacophore that eventually turned into potential clinical candidates 17 and 19. During development, a number of issues were successfully addressed, such as metabolic stability, plasma stability, GSH adduct formation, and aniline mutagenicity. Thus, careful modification of the molecule, such as conversion of the 1,4-dihydropyridinone to the 1,2-dihydropyridinone system, proper substitution at C-5", and in some cases addition of fluorine atoms to the aniline ring allowed for the identification of a novel class of potent P2X7 inhibitors suitable for evaluating the role of P2X7 in inflammatory, immune, neurologic, or musculoskeletal disorders.

  Chloramphenicol base chemistry. Part 11: 1 chloramphenicol base-derived thiourea-catalyzed enantioselective Michael addition of malononitrile to α , β -unsaturated ketones

  摘要：

  The first chloramphenicol base-derived thiourea-catalyzed enantioselective Michael addition of malononitrile to alpha,beta-unsaturated ketones is reported. The Michael adducts were obtained in good to excellent yields (up to 98% yield) and enantioselectivities (up to 94% ee). This reaction has a broad substrate scope to various alpha,beta-unsaturated ketones. With this in mind, this methodology was successfully applied to the synthesis of a chiral piperidone, an advanced building block for dihydropyridinone P2X(7) receptor antagonists.

  Abstract A family of novel squaramides/sulfamides based on 1,2-alkamine was developed as chiral bifunctional catalysts to promote the asymmetric alcoholysis of meso cyclic anhydrides. The hemiesters were obtained in high yield with up to 93% ee. The usefulness of this methodology was demonstrated in the asymmetric synthesis of the key intermediate of P2X7 receptor antagonists.

  The pilot-plant syntheses of 3 and 4, the core structures of a series of P2X7 antagonists are described. The sole stereogenic center in the dihydropyridinone ring was generated by catalytic desymmetrization. Selective formylation, followed by a tandem imination/lactamization sequence, produced the 3,4-dihydropyridin-2-one ring. The compounds 3 and 4 were produced at multikilogram scale in good overall

  A simple and practical route for the asymmetric synthesis of (S)-4-(4-fluorophenyl)-1,4,5,6-tetrahydro-6-oxo-3-pyridinecarboxylic acid (1) is presented. The procedure comprises catalytic desymmetrization of a meso-anhydride using a chiral thiourea organocatalyst, followed by selective formylation and cyclization.
