چکیده
The Ugi reaction offers an effective method for preparing chromophore-appended DOTA-monoamide ligands, which can readily be elaborated to their lanthanide complexes.

Controlling energy transfer in ytterbium complexes: oxygen dependent lanthanide luminescence and singlet oxygen formation.
Pyrene-appended ytterbium complexes have been prepared using Ugi reactions to vary the chromophore-lanthanide separation. Formation of the ytterbium(iii) excited state is sensitised via both the singlet and triplet excited states of the chromophore. Energy transfer from the latter is relatively slow, and gives rise to oxygen-dependent luminescence.
متن کاملSynthesis and Biological Evaluation of Novel Quinoline Derivatives as Antibacterial and Antifungal Agents
Vilsmeier Several diamide derivatives containing 2-chloroquinoline scaffolds were synthesized via Ugi reaction of 2-chloroquinoline-3-carboxaldehydes, amines, carboxylic acids and isocyanides. The diversity of these quinolinyl Ugi-adducts was increased by using 2-chloroquinoline-3-carboxylic acids as a source of acid. Among them, compounds 2d, 2n, 2p, 4a, 4c and<strong...
متن کاملManganese(II) complexes of scorpiand-like azamacrocycles as MnSOD mimics.
Mn(II) complexes of scorpiand-type azamacrocycles constituted by a tretrazapyridinophane core appended with an ethylamino tail including 2- or 4-quinoline functionalities show very appealing in vitro SOD activity. The observed behaviour is related to structural and electrochemical parameters.
متن کاملA novel intramolecular Ugi reaction with 7-azabicyclo[2.2.1]heptane derivatives followed by post-condensation acylations: a new entry to azanorbornyl peptidomimetics.
beta-amino acids have been employed in the past as bifunctional building blocks in intramolecular Ugi multicomponent reactions to yield beta-lactam derivatives. By using 7-azabicyclo[2.2.1]heptane-2-carboxylic acid, a different outcome has been observed and rationalised. The final compounds are polyfunctionalised azabicyclic peptidomimetics, and further elaboration can be achieved exploiting an...
متن کاملSynthesis of Novel Fluorene Bisamide Derivatives via Ugi Reaction and Evaluation their Biological Activity against Mycobacterium species
A series of new fluorene bisamide derivatives were synthesized through multi-component Ugi reaction and tested for their in vitro anti-mycobacterial activity. The structures of the products 5a-w were deduced from their IR, 1H NMR, and 13C NMR spectra. Elemental analyses (CHN) for novel compounds (5a, 5d, 5f, 5h, 5k, 5l, 5p, 5s, 5t, 5v, 5w) was done to. These compounds were evaluated as anti-bac...
