In his seminal work, 1 Rolf Huisgen defined 1, 3-dipolar cycloadditions as “1, 3-Dipole, abc,
must be defined, such that atom a posseses an electron sextet, that is, an incomplete …

This review highlights a number of additives that can be used to make asymmetric reactions
perfect. Without changing other reaction conditions, simply adding additives can lead to …

The stereocontrolled construction of chiral carbo-and heterocycles is a topic of paramount
importance in modern organic synthesis, driven by the predominance of chiral mono-and …

Organocatalysis offers a number of opportunities in polymer synthesis and was among the
earliest methods of catalyzing the synthesis of polyesters. In the following Perspective we …

The isoxazolidine ring represents one of the privileged structures in medicinal chemistry,
and there have been an increasing number of studies on isoxazolidine and isoxazolidine …

Asymmetric organocatalysis has experienced an incredible development since the
beginning of this century. The expansion of the field has led to a large number of efficient …

This review covers reactions where iminium ions are likely to be active intermediates in the
catalytic cycle. The focus of the review is on synthetically useful protocols and smallmolecule …

Catalytic asymmetric 1, 3-dipolar cycloadditions of azomethine ylides have turned out to be
one of the most efficient methods for the preparation of enantioenriched pyrrolidines. The …

Abstract The legacy of Gilbert Newton Lewis (1875–1946) pervades the lexicon of chemical
bonding and reactivity. The power of his concept of donor–acceptor bonding is evident in the …

Catalysis with chiral secondary amines (asymmetric aminocatalysis) has become a well‐
established and powerful synthetic tool for the chemo‐and enantioselective functionalization …
