protocol has been developed for the Minisci acylation reactions of nitrogen-containing heteroarenes with α-keto acids. Distinct from the conventional Minisci acylation conditions, the chemistry was performed using non-noble metal Fe(II), instead of expensive Ag(I) salt, as catalyst. A wide range of substrates, including aliphatic or aromatic α-keto acids, as well as various N-heteroarenes, proved to
A method for producing a biaryl compound represented by the formula (2)
Ar—Ar (2)
wherein Ar represents an aromatic group which can have a substituent, comprising conducting a coupling reaction of a compound represented by the formula (1)
Ar—Cl (1)
wherein Ar represents the same meaning as defined above, in the presence of copper metal and a copper salt.
The invention provides methods that relate to a novel therapeutic strategy for the treatment of cancer and inflammatory diseases. In particular, the method comprises administration of a compound of Formula I, or a pharmaceutically acceptable salt thereof, or a pharmaceutical composition comprising such compound admixed with at least one pharmaceutically acceptable excipient.
