(−)-9-Fluorocytisine, (−)-9-methylcytisine and (−)-9-trifluoromethylcytisine were synthesized from the natural product (−)-cytisine. 9-Methyl and 9-trifluoromethyl cytisines display a remarkable affinity at the α4β2 nicotinic receptor subty

Aiming at the development of green and efficient C–C bond formations (aldol and Mannich reactions), the decarboxylative nucleophilic addition of malonic acid half ester to imines or aldehydes under mild metal-free conditions was studied. A careful

A detailed study of the deracemization of pipecolic acid amides is reported. Enantioselective protonation of the lithium enolates of these amides with use of commercially available ephedrines led to enantiomeric excesses (ee values) higher than 99 %.

Tumor development leading to cancer is a complex process involving several steps. Among them, angiogenesis, ie growth of new tumor induced blood vessels is one of the most important therapeutic targets in the search for anticancer agents. One point w

An efficient approach to bis([1,2,4]-oxadiazol)benzaldehydes as well as the corresponding mono-benzaldehyde derivatives has been developed starting from benzamidoxime, which is readily obtained from 4-cyanobenzaldehyde. All these new compounds were s

The effect of lithium halides on the enantioselectivity of the addition of methyllithium on o-tolualdehyde, in the presence of chiral lithium amides derived from chiral 3-aminopyrrolidines (3APLi), has been investigated. The enantiomeric excess of th

It is shown that lyotropic liquid crystal mixtures made of poly-γ-benzyl- l -glutamate (PBLG) dissolved in N , N -dimethylformamide (DMF) are efficient anisotropic NMR solvents to distinguish the enantiomers of chiral amines through the effects of t
