Gold-catalyzed post-MCR transformations towards complex (poly)heterocycles

Publication date: Available online 28 August 2018Source: Drug Discovery Today: TechnologiesAuthor(s): Upendra K. Sharma, Guilong Tian, Leonid G. Voskressensky, Erik V. Van der EyckenPost multicomponent reaction (MCR) transformations are one of the most successful methods leading to high structural diversity and molecular complexity. A well-known MCR, the Ugi reaction typically affords a linear peptide backbone, enabling post-Ugi transformations as an elegant solution to rigidify the Ugi adduct into more drug-like species. Not surprisingly, the development of such transformations leading to new structural frameworks has expanded rapidly over the last few years. These reactions have reached an impressive level of performance and versatility, particularly in amalgamation with gold catalysis. This review outlines the developments achieved in the past decade, highlighting the modifications that are performed in a sequential or domino fashion with emphasis on major concepts, synthetic applications of the derived products as well as mechanistic aspects.Graphical abstractThis review highlights the recent advances towards post-MCR transformations towards complex (poly)heterocycles based on gold-catalyzed key steps.
