Synthesis of 7-β-(N,N-dialkylamino)ethoxy derivatives of natural isoflavones and 4-aryl-3-[2-hydroxy-4-β-(N,N-dialkylamino) ethoxy]phenylpyrazoles based on them

摘要

7-O-β-(N,N-dialkylamino)ethyl derivatives of formononetin, 2-methylformononetin, and cladrin were synthesized. Their recyclization through the action of hydrazine hydrate was studied. A series of 4-aryl-3-[2-hydroxy-4- β-(N,N-dialkylamino)ethoxy]phenylpyrazoles was obtained.
