The 2-azaphenalenyl radical 2 has been synthesized and characterized by ESR spectroscopy. Variable-temperature ESR measurements were carried out on both the phenalenyl (1) and the 2-azaphenalenyl (2) radicals. The phenalenyl radical 1 has the known propen

The invention relates to new piperidinyl-substituted pyridyl carboxamides of the general formula (I), wherein the structure element E has meanings (E1) or (E2) and whereby the heterocyclic ring can optionally have a double bond. These substances have especially high cytostatic activities and pronounced immunosuppressive properties which make them suitable for therapeutic treatment in broad tumor spectrum.

Optically active ferrocenylbisphosphine ligands containing 2-(dialkylamino)ethylamino group on the ferrocenylmethyl position have been prepared and used for the gold(I)-catalyzed asymmetric aldol reaction of isocyanoacetate with aldehydes. Six-membered ring amines, such as morpholino or piperidino group, at the terminal of the side chain were most stereoselective to give optically active trans-4- methoxycarbonyl-5-alkyl-2-oxazolines (up to 97% ee) with high enantio- and diastereoselectivity in a quantitative yield.
