Uracil derivatives form strong complexes with complementary 2,4-diaminotriazine and adenine compounds, whereas derivatives of 5-azauracil (2,4-dioxotriazine) are known to form weak complexes in aqueous medium. However, herein we report that in organic medium (CDCl3), the 5-azauracil moiety forms hydrogen-bond-mediated complexes with complementary(More)
A full theoretical study of the reaction between a novel type of ylide, i.e. nitrone ylides, and alkenes has been carried out. Both concerted and polar stepwise mechanisms have been considered. Only the zwitterionic mechanism predicts correctly the experimentally observed adducts. Depending on the level of theory, the mechanism moves from concerted to polar(More)
