Synthesis of Pyrazoles from 1,3-Diols via Hydrogen Transfer Catalysis
摘要:
1,3-Diols engage in ruthenium-catalyzed hydrogen transfer in the presence of alkyl hydrazines to provide 1,4-disubstituted pyrazoles. Regioselective synthesis of unsymmetrical pyrazoles from beta-hydroxy ketones is also described.
