Charged intermediates and reagents are ubiquitous in organic transformations. The
interaction of these ionic species with chiral neutral, anionic, or cationic small molecules has …

Recently, the use of enantiomerically pure counteranions for the induction of asymmetry in
reactions proceeding through cationic intermediates has emerged as an exciting new …

Recently, chiral highly acidic Brønsted acids have emerged as powerful catalysts for
enantioselective C C and C X bond‐forming reactions. Their strong acidity renders them …

Abstract Geladene Intermediate und Reagentien sind in organischen Transformationen
ubiquitär. Die Wechselwirkungen dieser ionischen Spezies mit chiralen neutralen …

Seit einiger Zeit hat sich die Verwendung enantiomerenreiner Gegenanionen zur Induktion
von Enantioselektivität in Reaktionen über kationische Intermediate als interessantes neues …

Herein we describe the development of a catalytic enantioselective alkynylogous
Mukaiyama aldol reaction. The reaction is catalyzed by a newly designed chiral …

Over the past decade, organocatalysis has emerged as a powerful tool for stereoselective
carbon–carbon bond formation under exceptionally mild conditions. The organocatalytic …

A chiral disulfonimide (DSI)‐catalyzed asymmetric reduction of N‐alkyl imines with Hantzsch
esters as a hydrogen source in the presence of Boc2O has been developed. The reaction …

Since RC Fuson formulated the principle of vinylogy, this platform has been extensively
developed through combining diverse predominant chemical transformations. Among them …

An asymmetric Torgov cyclization, catalyzed by a novel, highly Brønsted acidic dinitro‐
substituted disulfonimide, is described. The reaction delivers the Torgov diene and various …
