It is shown by IR and NMR studies that the xanthines 1-5 prefer a side-on complexation to the chiral dirhodium tetrakis[(R)-α-methoxy-a-(trifluoromethyl)phenylacetate] (Rh*) in solution whereas carbonyl groups are involved in the solid state. For 6, at le

Synthesis and physicochemical properties of N-benzyl pyrimido[2,1-f]purinediones are described. These derivatives were synthesized by the cyclization of 7-chloropropylo-8-bromo-1,3-dimethyl- or 1,3-dipropyl xanthine derivatives with corresponding (un)subs
