ODAP is an agonist of the ionotropic AMPA glutamate receptor. It is known to cause neurolathyrism in humans, a motor neuron degenerative disease characterized by degeneration of pyramidal-tract neurons in the spinal cord and in the area of the cortex controlling the legs, resulting in lower-body paralysis. There is not one direct explanation as to how ODAP causes neurolathyrism; however, there has been evidence to support a few biological effects.

WebFeb 3, 2024 · Here we report the design of chiral mono-protected aminomethyl oxazoline (MPAO) ligands that enable Pd (II)-catalyzed enantioselective β-arylation, -alkenylation, and -alkynylation of isobutyric amides ( Fig. 1B ). The remaining α-methyl group can then undergo further C–H functionalizations to afford greater product diversity. WebIn general, if you have a small molecule with no sp3 centers in the molecule, the molecule is planar. But there are many exceptions. Here are a few common ones: - Water is planar. The oxygen is sp3 but there are only 3 atoms so there's nothing to stick out of the HOH plane. - Allene is not planar.

WebMar 26, 2016 · Any chiral center can have two possible configurations, and these configurations are designated either R or S by convention (the letters R and S come from the Latin words for right and left, rectus and sinister ). If a molecule has a chiral center that is designated R, the chiral center will be S in the molecule's enantiomer.
