摘要:
The present invention is directed to compounds of formula (I): wherein R represents a methyl or an ethyl group X represents N, C-H or C-CH 3 when X represents C-H or C-CH 3 , Y represents N when X represents N, Y represents C-H and physiologically functional derivatives thereof, pharmaceutical compositions comprising the compounds, the use of the compounds for the manufacture of medicaments particularly for the treatment of inflammatory and/or allergic conditions, processes for the preparation of the compounds, and chemical intermediates in the processes for the manufacture of the compounds.
摘要:
Electroluminescent compounds, devices and methods for making the foregoing are disclosed, which employ a novel topological strategy for designing amorphous molecular solids suitable for forming thin films in optoelectronic devices. In this approach chromophores are attached to a tetrahdral point of convergence.

Novel non-steroidal ligands for the estrogen receptor which possess tissue-dependent estrogenic and antiestrogenic activity as well as methods for making the same and their applications in treating a variety of disease states.
摘要:
The present invention relates to a process for labeling compounds comprising thiol moieties with 3-arylpropiolonitrile compounds, to 3-arylpropiolonitrile compounds substituted with tag moieties and to specific 3-arylpropiolonitrile linkers.
摘要:
A method for increasing the rate of phosphine oxide reduction, preferably during a Wittig reaction comprising use of an acid additive is provided. A room temperature catalytic Wittig reaction (CWR) the rate of reduction of the phosphine oxide is increased due to the addition of the acid additive is described. Furthermore, the extension of the CWR to semi-stabilized and non-stabilized ylides has been accomplished by utilization of a masked base and/or ylide-tuning.
