The assembly of architecturally complex alkaloids embedding the indole nucleus is of
paramount importance for the target oriented synthesis of biologically active molecules. 1 A …

Dual hydrogen‐bond donor (HBD) scaffolds can be strategically designed to enable their
optimal performance as catalysts. The deliberate installation of activating groups on HBDs …

Chalcogen bonding is the non‐covalent interaction between Lewis acidic chalcogen
substituents and Lewis bases. Herein, we present the first application of dicationic tellurium …

An overview of the applications of boronic and borinic acids in catalysis is presented. Taking
advantage of the Lewis acidity of trivalent boron and the reversible covalent interactions of …

Chiral, neutral H-bond donors have found widespread use as catalysts in enantioselective
reactions involving ion-pair intermediates. Herein, a systematic mechanistic study of a …

A new metal–organic framework (MOF) composed of urea-containing tetracarboxylate struts
was synthesized, and its hydrogen bonding capabilities were evaluated. The catalytic …

Silanediols are introduced as a new class of hydrogen bond donor catalysts for the
activation of nitroalkenes toward nucleophilic attack. Excellent yields of product are obtained …

Chalkogenbrücken sind nicht‐kovalente Wechselwirkungen zwischen Lewis‐aziden
Chalkogensubstituenten und Lewis‐Basen. Hierin präsentieren wir die erste Anwendung …

A spectrophotometric sensor is described that provides a useful assessment of the LUMO-
lowering provided by catalysts in Diels–Alder and Friedel–Crafts reactions. A broad range of …

Bifunctional catalysts that contain a Brønsted-basic amine and a hydrogen-bond donor in
the same molecule have been very successful catalysts for numerous enantioselective …
