Several new 1,2,5-oxadiazole N-oxide derivatives and some deoxygenated analogues were synthesized to be tested as potential selective hypoxic cell cytotoxins. Compounds prepared were designed in order to gain insight int...

In this article we consider the problem of computing approximations to the second derivatives of functions of n variables using finite differences. We show how to derive different formulas and how to comput the errors of...

Fueron obtenidos diez derivados del ácido cinámico mediante la condensación del ácido malónico con diferentes benzaldehidos arilsustituidos en presencia de piperidina como catalizador, bajo irradiación de microonda...
