2-ARYLBENZOTHIOPHENE DERIVATIVES OR PHARCEUTICALLY ACCEPTABLE SALTS THEREOF, PREPARATION METHOD THEREOF, AND PHARCEUTICAL COMPOSITION FOR THE DIAGNOSIS OR TREATMENT OF DEGENERATIVE BRAIN DISEASE CONTAINING THE SAME AS ACTIVE INGREDIENT

2-arylbenzothiophene derivatives or pharmaceutically acceptable salts thereof, a preparation method thereof, and a pharmaceutical composition for the diagnosis or treatment of degenerative brain disease containing the same as an active ingredient. Since the 2-arylbenzothiophene derivatives of Formula 1 have a relatively high binding affinity for beta-amyloid, they can be used as diagnostic reagents for diagnosing Alzheimer’s disease at an early stage by non-invasive techniques when they are labeled with radioisotopes: wherein R1-R4, V, W, X, Y and Z are as defined in the Detailed Descript of the specification. Further, when the pharmaceutical composition containing the 2-arylbenzothiophene derivative binds with a low-molecular weight beta-amyloid peptide binding compound, generation of malignant high-molecular weight beta-amyloid deposits is minimized. Accordingly, the pharmaceutical composition can be used as a therapeutic agent of degenerative brain disease such as Alzheimer’s disease

Access to 4-alkylaminopyridazine derivatives via nitrogen-assisted regioselective pd-catalyzed reactions

3-Substituted, 6-substituted, and unsymmetrical 3,6-disubstituted 4-alkylaminopyridazines were prepared from a sequence of three chemo- and regioselective reactions combining amination and palladium-catalyzed cross-coupling reactions, such as reductive dehalogenation and Suzuki-Miyaura reactions. Extension of the methodology to Sonogashira reaction yielded a novel class of 3-substituted pyrrolopyridazines.

Palladium-catalyzed highly regioselective Mizoroki-heck arylation of allylamines with aryl chlorides

Palladium catalyst systems for the regioselective Mizoroki-Heck arylation of N,N-diprotected and N-protected allylamines with aryl chlorides have been developed. Pd(OAc)2 in combination with appropriate additives could efficiently catalyze the linear arylation of N,N-diprotected allylamines with aryl chlorides in toluene to give exclusively the gamma-arylated products in good to excellent yields and with excellent regio- and stereocontrol and good functional group tolerance. With use of a catalytic mixture of Pd(OAc) 2 and 1,1′-bis(diphenylphosphino)ferrocene, the arylation of N-protected allylamines with aryl chlorides could be accomplished in ethylene glycol/DMSO, which afforded complete beta-regioselectivity with good functional group tolerance. The steric and electronic properties of allylamine substrates are found to be critical to the catalytic activity and regiocontrol in both linear and internal arylations. Copyright
