Nature, 1953
INVESTIGATIONS in this department into the nature of the chrome tanning process have involved the preparation of various modified forms of collagen. Among possible modifications, the decarboxylation of collagen appeared to be of interest, although it has received scant attention from previous workers.

The Decarboxylative Blaise Reaction
The Journal of Organic Chemistry, 2007Reaction of aryl nitriles with potassium ethyl malonate in the presence of zinc chloride and a catalytic amount of Hünig's base provided beta-amino acrylates in moderate to good yield. Compared to the classical Blaise reaction, this reaction is safer (endothermic), devoid of lacrimatory reagent, and is possible with 0.5-1.0 equiv of zinc chloride.

Nonenzymatic decarboxylation of pyruvate
Analytical Biochemistry, 1984Triton X-100, retinol, retinoic acid, retinal, hexane, dithiothreitol, mercaptoethanol, and some other commercially available chemicals caused nonenzymatic decarboxylation of pyruvate and alpha-ketoglutarate. "Lipids" obtained from human or pigeon liver homogenates using isopropanol/hexane also had very high nonenzymatic decarboxylating activity on ...

Acidic Cannabinoid Decarboxylation
Cannabis & Cannabinoid Research, 2022Introduction: Cannabis is a valuable plant, cultivated by humans for millennia. However, it has only been in the past several decades that biologists have begun to clarify the interesting Cannabis biosynthesis details ...

The Decarboxylative Strecker Reaction
Organic Letters, 2011α-Amino acids react with aldehydes in the presence of a cyanide source to form α-amino nitriles in what can be considered a decarboxylative variant of the classical Strecker reaction. This unprecedented transformation does not require the use of a metal catalyst and provides facile access to valuable α-amino nitriles that are inaccessible by ...

Oxidative decarboxylation of naproxen
Journal of Pharmaceutical Sciences, 1992The decarboxylation of naproxen (1H) and its salt (1-) was achieved by means of chemical [Ce(IV) or S2O8(2-)] and electrochemical oxidation. The product patterns were compatible with mechanisms involving single-electron transfer from the pi-system or the carboxylate moiety.

Decarboxylation of Oxalacetate by Blood
Nature, 1948EVOLUTION of carbon dioxide from oxalacetate by washed rabbit erythrocytes at pH 7·4 has been reported previously1. Because of the solubility of carbon dioxide at that pH, this could at best be only a qualitative indication of the decarboxylation. Working in either phosphate or 2M acetate buffer, and measuring carbon dioxide formation by the standard ...
