Synthesis of various analog derivatives of ORG13514 as 5-HT1A ligands
摘要:
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.
[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.
