Special Issue Information

Dear Colleagues,

The synthesis of enantioenriched organic molecules plays a pivotal role in organic chemistry, having essential applications in the preparation of pharmaceutically relevant compounds. Indeed, enantiomers of bioactive compounds often possess very different pharmacological effects, and thus, the synthesis of enantiopure drugs and/or their intermediates remains a central topic for synthetic organic chemists.

Organocatalysis has proven to be an efficient and environmentally friendly alternative to the most common organometallic synthetic methodologies for the achievement of molecular structures in an enantioselective fashion. Certainly, several advantages associated with the employment of small organic molecules as catalysts have been identified: (1) various and simultaneous activation modes for substrates and reagents are possible; (2) these catalysts are, in general, cheaper, more readily available, and easier to synthesize than enzymes or metal complexes; (3) frequently, inert atmosphere and dry solvents are not necessary due to the high stability of the organocatalysts; and (4) organocatalysts can be successfully combined with metal catalysts to promote the cooperative activation of different substrates. Further, several research groups have focused on the development of innovative organocatalytic domino/one-pot reaction sequences to achieve highly diastereo- and enantioenriched complex molecular scaffolds, providing atom and step-economical synthetic methodologies.

The aim of this Special Issue is to advance the knowledge on organocatalytic methodologies for the asymmetric synthesis of enantioenriched organic compounds, involving also synergistic/cooperative catalysis and domino/one-pot reaction sequences. Moreover, studies on the use of organocatalytic methodologies in the total synthesis of potentially bioactive compounds are of interest.

Atropisomers, i.e., stereoisomers that are distinct because their free rotation about a single bond is hindered by steric interactions between nearby bulky groups or by electrostatics, may interact with their surroundings in different ways, and may also exhibit different properties. They may be found as natural products, as pharmaceutical or agricultural active ingredients, as chiral ligands and organocatalysts, and in functional materials. Our ability to synthesize them stereoselectively and in a sustainable way, using achiral materials and simply with the aid of an organocatalyst and mild conditions, has become a hot topic in research. This review provides an overview of recent achievements in the synthesis of atropisomers containing C-N and N-N axes of chirality. Full article
