A new synthesis of phosphoryl-enolpyruvic acid.
While investigating the enzymatic conversion of n-glyceric acid-3phosphoric acid to pyruvic acid and phosphoric acid, an essential step both in glycolysis and fermentation, Meyerhof and Lohmann (1) observed the formation of a hitherto unknown organic phosphoric acid ester. They succeeded in isolating the new intermediary compound by virtue of the ease of crystallization of the silver-barium sal...
متن کاملPhosphoryl Guanidines: A New Type of Nucleic Acid Analogues
A new type of nucleic acid analogues with a phosphoryl guanidine group is described. Oxidation of polymer-supported dinucleoside 2-cyanoethyl phosphite by iodine in the presence of 1,1,3,3-tetramethyl guanidine yields a dinucleotide with an internucleoside tetramethyl phosphoryl guanidine (Tmg) group as the main product. The Tmg group is stable under conditions of solid-phase DNA synthesis and ...

A New Synthesis of Glutamic Acid*
Glutamic acid has been prepared previously by the racemization (1) of the natural dextro form and by three synthetic methods. The first synthesis, that by Wolff (2) in 1890, is principally of theoretical interest as it involves the preparation of six intermediate substances starting with levulinic acid and the yield of final product is not given. In 1925 Knoop and Oesterlin (3) obtained 1.1 gm....
متن کاملA new synthesis of lysergic acid.
[reaction: see text] (+/-)-Lysergic acid has been synthesized via an economical 8-step route from 4-bromoindole and isocinchomeronic acid without the need to protect the indole during the synthesis. Initial efforts to form the simpler 3-acylindole derivatives first and then cyclize these were unsuccessful in the cyclization step.
