useful for the treatment of depression, obsessive compulsive disorder, panic attacks, generalized anxiety disorder, social anxiety disorder, sexual dysfunction, eating disorders, obesity, addictive disorders caused by ethanol or cocaine abuse, and dysthymia.
Summary: New compounds (3 and 4) possesing the 2,3-dihydro-1,4-dioxino[2,3-b]pyridine group were synthesized and tested as calcium antagonist agents. Both of them showed moderate anticalcium activity.
In connection with the development of new potential 5-HT1A ligands, multistep synthesis of N-substituted-3-aminomethyl-2,3-dihydro-1,4-dioxinol[2,3-b]pyridine derivatives as ORG13514 analogs are described. Their biological activity as 5-HT1A type ligands is reported and compared with ORG13514 affinity and selectivity for 5-HT1A receptors. (C) 1999 Elsevier Science S.A. All rights reserved.
Synthesis of 2-Substituted-2,3- dihydro-1,4-dioxino[2,3-<i>b</i>]pyridine Derivatives
[GRAPHICS]A variety of 2-substituted-2,3-dihydro-1,4 dioxino[2,3-b]pyridines B have been synthesized from the readily available 2-nitro-3-oxiranylmethoxypyridine 1 via a Smiles rearrangement. We demonstrate how variations of reaction conditions affect the product distribution of A and B.
