Esta estrutura foi posteriormente confirmada por Robert B. Acta54 Acta65 O isolamento provocado pela guerra exigia bom uso do almoxarifado.

In this context, the present account describes the importance of this structural property in the medicinal chemistry of different classes of bioactive compounds or therapeutic agents, emphasizing how atropisomerism could affect the molecular recognition of a ligand or a prototype by the target bioreceptor.

Vladimir Prelog and the stereochemistry of organic molecules: Acta38 Acta33 Acta35 Atropisomerism is a special kind of stereoisomeric relationship that arises from the freezing of a certain conformation of an organic molecule, associated with esteroequimica high rotational barrier about a single covalent bond. Cahn e Christopher Ingold apresentaram uma nova proposta para os descritores D e L.

Atropisomerism: the effect of the axial chirality in bioactive compounds

Atropisomeric compounds, intermediates and catalysts have well-know importance in organic synthesis, but the influence of the axial chirality in substances able to modulate biological systems is still not very exploited in drug design and development.
