The present invention relates to triaminopyrimidine derivatives of formula (I)
where Y, R3, W, R4a, R5a, R4b, R5b, n and m are variable. These compounds have CDC25 phosphatase-inhibiting activity and can therefore be used as drugs in diseases in which CDC25 phosphatases are involved. The invention also relates to pharmaceutical compositions containing said products and methods of using the drug.

La présente invention a pour objet des dérivés tri-amino-pyrimidine de formule générale (I) dans laquelle Y, R3, W, R4a, R5a, R4b, R5b, n et m sont variables. Ces composés présentent une activité inhibitrice des phosphatases CDC25 et sont donc susceptibles d'être utilisés comme médicaments dans les pathologies dans lesquelles les CDC25 sont impliquées. L'invention concerne également des compositions pharmaceutiques contenant lesdits produits et leur utilisation pour la préparation d'un médicament.

Addition of prochiral cyclic 1,3‐diketones to Michael acceptors applying bifunctional Cinchona‐derived squaramides resulted in chiral adducts with stereoselectivities of up to 99% ee and allowed for desymmetrization of the nucleophile. These labile hemiacetal intermediates were transformed to new 1,4‐dihydropyridines with high diastereoselectivities and no erosion of optical purity. Their further oxidation
