Straightforward stereoselective synthesis of polyfunctionalised cyclohexenols using a multicomponent approach
摘要:
An intramolecular Ugi 5-centre-4-component reaction (U-5C-4CR) followed by a palladium-catalysed ring-opening has been employed to transform oxabicycloheptene-based beta-amino acids into two families of regioisomeric polyfunctionalised cyclohexenols. The whole process is completely stereoselective and enantiomerically pure products are obtained in high overall yields. (C) 2010 Elsevier Ltd. All rights reserved.

We report on the use of a diversity oriented synthesis (DOS) approach that resulted in the generation of a set of libraries of compounds presenting novel structural cores. These chemical cores have been employed to design potential antagonists of the antiapoptotic protein Bcl-x(L) through reiterated steps of molecular docking calculations followed by experimental verification of binding. Our data suggest that the DOS approach is suitable to generate novel scaffolds, which can be employed to target protein-protein interactions.
