3-b]furan-4,9-diones has been developed by N-iodosuccinimide (NIS)-induced enone difunctionalization with 2-hydroxy-1,4-naphthoquinones. This reaction involved sequential Michael addition, intramolecular oxidative cyclization and dehydrogenative aromatization to form new C–C and C–O bonds at the α and β positions of the enones. Various enones survived under the reaction conditions and the corresponding products

A novel consecutive one-pot synthesis of pyrazolines and pyrazoles starting from simple arylhalides, styrenes, carbon monoxide, and hydrazines has been established. Palladium-catalyzedcarbonylative vinylation of arylhalides gave the corresponding chalcones, which are trapped in situ by addition of hydrazines.
The invention provides specific small molecule compounds that allosterically regulate the activity or modulate protein-protein interactions of AGC protein kinases and the Aurora family of protein kinases, methods for their production, pharmaceutical compositions comprising same, and their use for preparing medicaments for the treatment and prevention of diseases related to abnormal activities of AGC protein kinases or of protein kinases of the Aurora family.
