Project

Synthesis of nonracemic helical aromatics employing transition metal catalysis (GA203/07/1664)

We will pay attention to an efficient asymmetric synthesis of helicenes on a preparative scale proposing four independent ways how to reach this goal: (a) diastereoselective [2+2+2] cyclotrimerisation of aromatic triynes containing two asymm...

Stereodirecting effects of deoxofluorination at C-3 and C-4 of 2-azido-2-deoxy-hexopyranosyl donors (GA17-18203S)

Stereoselective formation of a glycosidic bond remains the main challenge associated with the chemical synthesis of complex glycostructures. The influence of substituents at remote positions of the pyranose ring on the diastereoselectivity o...

Project

Enzymes as aymmetric catalysts in transformations of organic molecules and biomolecules (OC D10.10)

The investigation of enzymic reactions will be provided under the non-classic conditions (e.g. in organic solvents or under the effect of the microwave irradiation). Its main goal will be focused on developing ways of enzymic synthesis of chiral comp...

The asymmetric Michael-type addition reaction in the synthesis of biologically active compounds (OC D12.10)

Different ways of application of aldol and Michael-type addition reaction to the carbonyl functionality will be investigated in the project. Its main goal consists in developing convenient ways of synthesis of biologically active compounds. Depending...
