enantioselective remote C–H activation using a catalytic amount of a chiral norbornene as a transient mediator, which relays initial ortho-C–H activation to the meta position. This was used in the enantioselective meta-C–H arylation of benzylamines, as well as the arylation and alkylation of homobenzylamines. The enantioselectivities obtained using the chiral transient mediator are comparable across different

A general and greener protocol for the synthesis of aryl phosphonates by the cross-coupling of aryl halides and diethyl phosphite using tetrakis(triphenylphosphine)palladiume/triethylamine/polyethyleneglycol 600 [Pd(PPh3)4/Et3N/PEG 600] as an efficient catalytic system has been developed. This procedure also avoids hazardous solvents and is therefore an eco-friendly alternative to the existing methods

Anilinoalkynylpyrimidines were prepared and evaluated as dual EGFR/ErbB2 kinase inhibitors. A preference was found for substituted phenyl and heteroaromatic rings attached to the alkyne. In addition, the presence of a potential hydrogen bond donor appended to this ring was favored. Selected molecules in the series demonstrated some activity against human tumor cell lines.
