A novel copper-catalyzed [3+2] cycloaddition reaction with concomitant in situ generation of benzoylacrylonitriles and nitrile imines from phenacylmalononitriles and hydrazonoyl chlorides, respectively, is reported. The reaction was performed using copper(I) chloride as catalyst and N-methylimidazole as a clean complexing agent/weak base to afford the functionalized 4-benzoyl-5-cyanopyrazoles in moderate to good yields and excellent regioselectivity under ambient conditions. This method provides rapid access to a wide range of highly functionalized 4-benzoyl-5-cyanopyrazoles.

Solvent-free reaction of substituted a-haloketones with malononitrile in the presence of diethylamine provides an efficient one-pot synthesis of 2-amino-5-aryl (alkyl)-3-furonitriles in high yield.
COMPOUND FOR INHIBITING TYROSINE KINASE ACTIVITY OF DDR2 PROTEIN
-
Page/Page column 34; 36, (2010/02/14)
A new furopyrimidine compound, their pharmaceutically acceptable salt, and a tyrosine kinase activity inhibitor. The furopyrimidine compound is a compound defined by chemical formula 1, 2, 3 or 4, on their precursor, and can exist as a form of free base or in an acid-addition salt. Since the furopyrimidine compound has an effect of inhibiting activity of DDR2 tyrosine kinase, it can be used in treating illnesses caused by the DDR2 tyrosine kinase activity such as hepatocirrhosis, rheumatoid arthritis or cancer.
