In organic chemistry, anti-periplanar, or antiperiplanar, describes the A−B−C−D bond angle in a molecule. In this conformer, the dihedral angle of the...

ketoximes and N-chloro/N-fluoro imines, with the migrating group being anti-periplanar to the leaving group on the nitrogen. Certain conditions have been...

stereochemistry of the starting material. E2 eliminations require anti-periplanar geometry, in which the proton and leaving group lie on opposite sides...

(+sc or −sc, depending on the enantiomer), anti butane is anti-periplanar, and eclipsed butane is syn-periplanar. Klyne, W & Prelog V. Description of steric...

pyranosides is unreactive. Hyperconjugation is involved when OH-4 is anti-periplanar to the ring oxygen, which can also reduce its reactivity. (Scheme 3)...

one from equatorial glycosides as long as the donating orbital is anti-periplanar to the accepting orbital. Three angles are described by φ, ψ and ω...

stereochemistry arises due to hyperconjugative stabilization arising from the anti-periplanar interaction between the C-X antibonding σ* orbital and the forming...

clinal a torsion angle between 0° and 30° or 150° and 180° is called periplanar (p) a torsion angle between 0° to 30° is called synperiplanar or syn-...

effect of anti-periplanar orientation is also visible in comparing glucopyranose and galactopyranose hydrolysis. Glucopyranose has an anti-perplanar orientation...

clinal (c) a torsion angle between 0° and ±30° or ±150° and 180° is called periplanar (p) a torsion angle between 0° and ±30° is called synperiplanar (sp),...

clinal (c) and those between 0° and ±30° or ±150° and 180° are called periplanar (p). The two types of terms can be combined so as to define four ranges...
