NAD(P)H-NAD(P)+ Models. 73. Structure-Stereochemistry Relationship in the Reaction of NAD Analog
Four different NAD(P)H analogs have been oxidized by various substituted and unsubstituted 1,4-benzoquinones in the presence or absence of magnesium ion.The stereospecificity of the reaction depends not only on the reactivity of quinone but also on that of the analogs as well as on the presence or absence of magnesium ion.The results are discussed from the viewpoint of reaction mechanism for the transfer of a (net) hydride ion.
Spontaneous Resolution of an Axially Dissymmetric 3-Carbamoylpyridinium Iodide; Intrinsic Discrimination between the Enatiomeric Forms by the Introduction of a Second Chiral Element
The direction of the carbonyl-orientation in a solid amide-rotamer of 3-carbamoyl-1,2,4-trimethylpyridinium iodide is governed by the (R)-chirality in the amide side chain; structures, as determined by X-ray analysis and c.d
