Auxiliary-assisted palladium-catalyzed halogenation of unactivated C(sp3)-H bonds at room temperature

The direct transformation of unactivated C(sp3)-H bonds into C-halogen bonds was achieved by palladium catalysis at room temperature with good functional group tolerance. Some drugs and natural products were readily modified by this method. Merged with substitution reaction, newly formed C-X bonds can be transformed into diverse C-O, C-S, C-C and C-N bonds. A preliminary mechanism study demonstrates that solvent is crucial for C-H activation and the C-H activation step is involved in the rate-limiting step. An isolated Pd(ii) intermediate can be transformed into a halogenated product with the retention of conformation which suggests that concerted reductive elimination from Pd(iv) to form a C-X bond was favored.

Room-temperature copper-catalyzed arylation of dimethylamine and methylamine in neat water

The first room-temperature copper-catalyzed arylations of dimethylamine and methylamine in neat water have been developed. Using a combination of CuI and 6,7-dihydroquinolin-8(5 H)-one oxime as catalyst, dimethylamine is arylated with various aryl halides to give the corresponding products in good to excellent yields. Further, this catalysis enables the selective arylation of methylamine to afford the high yields of monoarylated methylamines as the sole products.

A highly efficient Cu-catalyst system for N-arylation of azoles in water

6,7-Dihydroquinolin-8(5H)-one oxime (L3) was found to serve as a superior ligand for the CuI-catalyzed N-arylation of imidazoles with aryl iodides, bromides, and electron-deficient chlorides in water. Moreover, the CuI/L3 catalyst system enabled the coupling reactions to take place smoothly with high yields under a low catalyst loading (0.1-1 mol% CuI and 0.2-2 mol% L3).

AMD070, a CXCR4 chemokine receptor antagonist: Practical large-scale laboratory synthesis

An efficient and convergent four-step synthetic route to the CXCR4 chemokine receptor antagonist AMD070 (1) has been developed which employs only a single chromatographic step in the entire sequence. Novel reductive amination methods have been developed for the coupling of 2 and 3 in which a dehydrative imine formation is followed by reduction with an attenuated borohydride reagent (zinc chloride and sodium borohydride). Selective extraction methods were employed to purify synthetic intermediates and remove reagents and impurities. A procedure has also been developed to isolate 1 in a pure crystalline form.
