  Synthesis and biological evaluation of antiplatelet 2-aminochromones

  摘要：

  The synthesis and biological evaluation of a series of antiplatelet 2-morpholinylchromones has been described. Modification of the C-7 phenylmethoxy group of 8-methyl-7-(phenylmethoxy)-2-(4-morpholinyl)-4H-1-benzopyran-4-one (2) has led to the discovery of a series of 7-[(amino-ethyl)oxy]-8-methyl derivatives which are potent inhibitors of ADP-induced platelet aggregation. Several members of this class proved active in preventing platelet-dependent thrombus formation in the dog, including 8-methyl-7-[2-(4-methyl-1-piperazinyl)ethoxy]-2-(4-morpholinyl)-4H-1-benzopyran-4-one (39) which was devoid of hemodynamic effects at the effective antithrombotic dose.

• A novel synthesis of 2-aminochromones via phosgeniminium salts

  A novel method for the synthesis of antiplatelet 2-aminochromones making use of the reaction of 2'-hydroxyacetophenone-BF2 Complexes with phosgeniminium chlorides has been developed. Aqueous hydrolysis of the intermediate beta-chlorovinylogous amide-BF2 complex affords the 2-aminochromone in good yield, without the need for chromatographic purification.
