Stereochemistry focuses on stereoisomers, red boxes in the picture. In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. [1][2] This contrasts with ...
Stereochemistry, a subdiscipline of chemistry, studies the spatial arrangement of atoms that form the structure of molecules and their manipulation. [1] The study of stereochemistry focuses on the relationships between stereoisomers, which by definition have the same molecular formula and sequence of bonded atoms (constitution), but differ in ...
In organic chemistry, the Le Bel–Van 't Hoff rule states that the number of stereoisomers of an organic compound containing no internal planes of symmetry is 2n, where n represents the number of asymmetric carbon atoms. French chemist Joseph Achille Le Bel [1] and Dutch chemist Jacobus Henricus van 't Hoff [2] both announced this hypothesis ...
The atropisomer is an iodoaryl compound synthesised starting from (S)- valine and exists as the (M,S) isomer and the (P,S) isomer. The interconversion barrier between the two is 24.3 kcal / mol (101.7 kJ /mol). The (M,S) isomer can be obtained exclusively from this mixture by recrystallisation from hexanes.
Stereoselectivity. In chemistry, stereoselectivity[1] is the property of a chemical reaction in which a single reactant forms an unequal mixture of stereoisomers during a non- stereospecific creation of a new stereocenter or during a non-stereospecific transformation of a pre-existing one. [2] The selectivity arises from differences in steric ...
Stereocenter. In stereochemistry, a stereocenter of a molecule is an atom (center), axis or plane that is the focus of stereoisomerism; that is, when having at least three different groups bound to the stereocenter, interchanging any two different groups creates a new stereoisomer. [1][2] Stereocenters are also referred to as stereogenic centers.
Stereospecificity. In chemistry, stereospecificity is the property of a reaction mechanism that leads to different stereoisomeric reaction products from different stereoisomeric reactants, or which operates on only one (or a subset) of the stereoisomers. [1][2][3] In contrast, stereoselectivity [1][2] is the property of a reactant mixture where ...
Conformational isomerism. Rotation about single bond of butane to interconvert one conformation to another. The gauche conformation on the right is a conformer, while the eclipsed conformation on the left is a transition state between conformers. Above: Newman projection; below: depiction of spatial orientation.
