Application of Photoclick Chemistry for the Synthesis of Pyrazoles via 1,3-Dipolar Cycloaddition between Alkynes and Nitrilimines Generated In Situ

The photochemical extrusion of gaseous nitrogen from 2,5-disubstituted tetrazoles to generate reactive nitrilimines in situ represents an efficient and attractive way to form dipoles that can be used to provide useful chemicals via 1,3-dipolar cycloadditions. The concept of “photoclick chemistry” already inspired numerous researchers, who exploited photochemical processes involving alkenes for the synthesis of adducts or the functionalization of biocompatible materials. The approach requires bioorthogonality, ease of access to the starting materials and operational simplicity. We report herein our investigations toward a photoclick reaction involving 2,5-disubstituted tetrazoles and alkynes as the dipolarophile for the synthesis of pyrazole derivatives. In addition to the numerous reports recently published on the synthesis of pyrazoles, we wish to add to the list a photochemical procedure that represents a mild and atom-economical alternative. Moreover, considering that such nitrilimines precursors can be accessed in one step from inexpensive and abundant starting materials and given the commercial availability of a broad spectrum of alkynes, we examined the scope of the photoclick reaction with respect to reactive partners, enabling the synthesis of a library of useful heteroaromatics.

Use of an angiotensin II receptor antagonist for the preparation of drugs to increase the survival rate of renal transplant patients

The present invention relates to the use, for the preparation of drugs to increase the survival rate of transplant patients, including renal and heart transplant patients, of a therapeutically effective amount of an angiotension II receptor antagonist compound, such as the class of substituted imidazoles represented by formula (I) and in particular by losartan potassium, 2-butyl-4-chloro-[(2′-tetrazol-5-yl)biphenyl-4-il]methyl]-5-(hydroxymethyl)imidazole potassium salt.
