Abstract:
The present invention is directed to phenyl carboxamide compounds which are inhibitors of the beta-secretase enzyme and that are useful in the treatment of diseases in which the beta-secretase enzyme is involved, such as Alzheimer's disease. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the treatment of such diseases in which the beta-secretase enzyme is involved.
Abstract:
Described herein is a production method of sulfonated polyarylene that is safe and enables easy control of the amount and position of sulfonic groups introduced in the polymer. The sulfonated polyarylene is also disclosed. The invention further provides a polyarylene and an aromatic sulfonate derivative that are suitably employed in the above production method. Also provided are a macromolecular solid electrolyte that comprises the sulfonated polyarylene, and a proton conductive membrane. The aromatic sulfonate derivative has the following formula (1): 1 wherein X is a halogen atom other than fluorine, a nullOSO3CH3 group or a nullOSO3CF3 group; Y is a divalent organic group; A is null(CH2)mnull or null(CF2)mnull (wherein m is an integer of 1 to 10); and R is a C4-20 hydrocarbon group. The production method of sulfonated polyarylene comprises coupling polymerization of an aromatic compound that includes at least the aromatic sulfonate derivative of the formula (1) and hydrolysis of the resultant polyarylene.
Abstract:
A two-step method is disclosed for chemically synthesizing substituted butadiene polymers from 1,4-disubstituted butynes. The first step in the synthesis of the butadiene polymer is the polymerization of 1,4-disubstituted butyne monomers. The substituted butyne polymer which results is then isomerized to the corresponding substituted butadiene polymer by subjecting the butyne to a weak organic base such as triethylamine. The isomerization reaction can be performed under very mild conditions and proceeds at ambient temperature.
