The present invention relates to compounds of Formula (I)
and their pharmaceutically acceptable salts, wherein the substituents are as described herein, and their use in medicine, in particular as Trk antagonists.
catalytic amount of Fe(TPP)Cl and Zn dust. The reaction precludes the traditional, more favored click reaction between an organic azide and alkynes, and instead proceeds by an unprecedented metalloradicalactivation. The method is anticipated to advance access to the construction of important basic nitrogen heterocycles, which will in turn enable discoveries of new drug candidates.

The present invention relates to novel pyridinylhydrazide derivatives and a method for manufacturing the same. The pyridinylhydrazide derivatives of the present invention have excellent antifungal and fungicidal activities, and thus will be useful for the prevention and treatment of various fungal infections. Additionally, the pyridinylhydrazide derivatives of the present invention, unlike other fungicidal preparations, can be orally administered.
Compounds of Formula I are useful as antagonists of TRPM8. Such compounds are useful in treating a number of TRPM8 mediated disorders and conditions and may be used to prepare medicaments and pharmaceutical compositions useful for treating such disorders and conditions. Examples of such disorders include, but are not limited to, migraines and neuropathic pain. Compounds of Formula I have the following structure:
where the definitions of the variables are provided herein.
intermolecular benzylic C(sp3)–H amination is developed utilizing 1,2,3,4-tetrazole as a nitrene precursor via iron catalysis. This method enables direct installation of 2-aminopyridine into the benzylic and heterobenzylic position. The methodselectively aminates 2° benzylic C(sp3)–H bond over the 3° and 1° benzylic C(sp3)–H bonds. Experimental studies reveal that the C(sp3)–H amination undergoes via the formation
