Palladium-catalyzed asymmetric three-component reaction between glyoxylic acid, sulfonamides and arylboronic acids for the synthesis of α-arylglycine derivatives

Autor: Bastian Jakob, Andreas M. Diehl, Kathrin Horst, Harald Kelm, Georg Manolikakes

Publikováno v: Frontiers in Chemistry, Vol 11 (2023)

A palladium-catalyzed asymmetric three-component synthesis of α-arylglycine derivatives starting from glyoxylic acid, sulfonamides and arylboronic acids is reported. This novel, operationally simple method offers access to the α-arylglycine scaffol

Oxyenamides as Versatile Building Blocks for a Highly Stereoselective One‐Pot Synthesis of the 1,3‐Diamino‐2‐ol‐Scaffold Containing Three Continuous Stereocenters

Autor: Harald Kelm, Philipp Kramer, Georg Manolikakes, Michael Bolte, Sara-Cathrin Krieg, Jennifer Grimmer

Publikováno v: Angewandte Chemie (International Ed. in English)

A highly diastereoselective one‐pot synthesis of the 1,3‐diamino‐2‐alcohol unit bearing three continuous stereocenters is described. This method utilizes 2‐oxyenamides as a novel type of building block for the rapid assembly of the 1,3‐di

A Enamide-based diastereoselective synthesis of isoindolo[2,1-a]quinolin-11(5H)-ones with three contiguous stereogenic centers

Autor: Miro Miro Halaczkiewicz, Harald Kelm, Georg Manolikakes

A stereoselective synthesis of isoindolo[2,1-a]quinolin-11(5H)-ones containing three contiguous stereogenic centers is described. This Lewis-acid mediated reaction of enamides with N-aryl- affords the desired fused heterocyclic isoindolinones in high
