Carbonylative Suzuki–Miyaura Coupling of 1‐Iodoglycals Mediated by the N ‐Heterocyclic Carbene Catalyst PEPPSI: Preparation of C ‐Acyl Glycosides

Eurípedes de Aguiar, Mônica F. Z. J. Toledo, Flávia Manarin, João H. de Araujo‐Neto et autres

Suzuki–Miyaura coupling has been widely explored, particularly in the development of pharmaceutically relevant structures. Its carbonylative variant enables the insertion of a CO bridge, granting access to a variety of bioactive biaryl ketone scaffolds. Herein, we describe a carbonylative Suzuki–Miyaura strategy for …

Synthesis and Phytotoxic Evaluation of 3-Indolylglycine Derivatives as New Natural-Like Herbicides

Alexandra Amaral, Júlia Biz Willig, Conceição Olguin, Isadora Sousa de Oliveira et autres

A novel class of potential herbicides, 3-indolylglycines were synthesized using an effective, green and rapid approach via multicomponent reaction (aza-Friedel-Crafts) between indoles, aldehydes and anilines in a water/sodium dodecyl sulfate system. The main advantages of this methodology are ease of handling, scalable …

Stereo‐ and Regioselective Cu‐Catalyzed Hydroboration of Alkynyl Chalcogenoethers

Isadora M. de Oliveira, Henrique Esteves, Mariana P. Darbem, Arthur Sartorelli et autres

Abstract A mild stereo‐ and regioselective Cu‐catalyzed hydroboration method for the synthesis of (Z)‐seleno‐alkenyl boronates and (Z)‐thio‐alkenylboronates from internal alkynes in the presence of commercially available B2pin2 is presented. This highly selective transformation relies on the use of N‐heterocyclic carbene (NHC) complex …
