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

Since the groundbreaking reports by the groups of Akiyama and Terada on the use of BINOL-
derived phosphoric acids as organocatalysts, 1, 2 the area of enantioselective Brønsted acid …

The addition of electrophilic reagents to the carbon–carbon double bond is one of the most
fundamental reactions in organic chemistry. Halogen electrophiles constitute probably the …

Seit einiger Zeit hat sich die Verwendung enantiomerenreiner Gegenanionen zur Induktion

Using cinchona alkaloid-derived primary amines as catalysts and aqueous hydrogen
peroxide as the oxidant, we have developed highly enantioselective Weitz–Scheffer-type …

The [3, 3]-diaza Cope rearrangement is a powerful synthetic principle that can be utilized to
generate a CÀC bond at the expense of an NÀN bond. It forms the basis of important and …

Counteranion control enables the enantioselective, organo Lewis acid catalyzed Hosomi-
Sakurai reaction of (hetero) aromatic aldehydes and allylsilanes using an easily handled …

The direct catalytic three-component coupling of aldehydes (1), carbamates (or amines; 2),
and nontoxic allyltrimethylsilane (3) is a very effective approach to homoallylic amine …

The combination of Lewis acid organocatalysis and internal hydrogen‐bond assistance was
used to develop a new type of highly active disulfonimide catalyst. The increased Lewis …

The Parham cyclization–intermolecular α-amidoalkylation sequence results in the facile
