A simple and practical protocol for the cross-coupling of methanesulfonamide and aryl iodides under ligand-freecopper(I)-oxide-catalyzed conditions in water is reported. The method allows the preparation of a wide variety of synthetically useful N-arylated methanesulfonamides in good to excellent yields (up to 90 %) under the optimized conditions.

A novel gold-catalyzed tandem intermolecular ynamide amination/C–H functionalization has been developed. A variety of highly functionalized 2-aza-1,3-butadienes can be obtained readily by utilizing this strategy. In addition, α-imino gold carbene intermediates are proposed in this amination reaction and with support by DFT (density functional theory) calculations.

The present invention relates to a pyrimidine compound represented by the following formula [I]
wherein each symbol is as defined in the specification, a pharmaceutically acceptable salt thereof, and a pharmaceutical agent for the prophylaxis or treatment of a disease caused by undesirable cell proliferation, particularly an antitumor agent, which contains such compound. The compound of the present invention has superior undesirable cell proliferation suppressing action, particularly, an antitumor action, and is useful as an antitumor agent for the prophylaxis or treatment of cancer, antirheumatoid agent and the like. In addition, by the combined use with other antitumor agent such as alkylating agent, metabolism antagonist and the like, it can be a more effective antitumor agent.
The present invention discloses compounds of Formula (I), or pharmaceutically acceptable salts, esters, or prodrugs thereof:
which inhibit Respiratory Syncytial Virus (RSV). The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from RSV infection. The invention also relates to methods of treating an RSV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.
