Control of Reactions of Pyruvates by Catalysts: Direct Enantioselective Mannich Reactions of Pyruvates Catalyzed by Amine-based Catalyst Systems.

Organic Letters, 2022
Enantioselective Mannich reactions of pyruvates catalyzed by amine-based catalyst systems, in which pyruvates act as nucleophiles, are reported. The reactions of pyruvates and cyclic sulfonylimines afforded the desired Mannich products, including those ...

Metabolic Reprogramming and Inflammatory Response Induced by D-Lactate in Bovine Fibroblast-Like Synoviocytes Depends on HIF-1 Activity

Frontiers in Veterinary Science, 2021
Acute ruminal acidosis (ARA) occurs after an excessive intake of rapidly fermentable carbohydrates and is characterized by the overproduction of D-lactate in the rumen that reaches the bloodstream.

Adenosine Triphosphate and Carbon Efficient Route to Second Generation Biofuel Isopentanol. [PDF]

, 2020
Climate change necessitates the development of CO2 neutral or negative routes to chemicals currently produced from fossil carbon. In this paper we demonstrate a pathway from the renewable resource glucose to next generation biofuel isopentanol by pairing

OBO-Protected Pyruvates as Reagents for the Synthesis of Functionalized Heteroaromatic Compounds.

Organic Letters, 2018
Pd-catalyzed α-arylation of methyl-OBO-ketone (OBO = 4-methyl-2,6,7-trioxabicyclo[2.2.2]octan-1-yl) gives rise to arylated OBO-protected pyruvates. By appropriate prefunctionalization of the aryl ring or by subsequent functionalization at the α-carbonyl ...
