Overcoming Challenges in Small-Ring Transfer: Direct Decarboxylative Hydroalkylation of Alkenes via Iron-Thiol Catalysis. [PDF]

open access: yesAngew Chem Int Ed Engl
Herein, we present a catalytic approach for the direct decarboxylation of challenging CF3‐cyclopropyl and cyclobutyl carboxylic acids using cooperative iron‐thiol catalysis. This strategy enables the efficient generation of valuable radicals that can be incorporated into activated and unactivated alkenes, offering access to elusive chemical space ...

Entry to 2-aminoprolines via electrochemical decarboxylative amidation of N‑acetylamino malonic acid monoesters [PDF]

open access: yesBeilstein Journal of Organic Chemistry
The electrochemical synthesis of 2-aminoprolines based on anodic decarboxylation–intramolecular amidation of readily available N-acetylamino malonic acid monoesters is reported. The decarboxylative amidation under Hofer–Moest reaction conditions proceeds

Metabolism of Tryptophan in the Liver: Interference with Decarboxylation of Other Aromatic Amino Acids

open access: yesActa Medica, 2000
Decarboxylation of aromatic amino acid in mammalian tissues is catalyzed by aromatic amino acid decarboxylase (EC. 4.1.1.28, AAD). The enzyme differs in its affinity to individual aromatic amino acids, the best substrates being 3,4-dihydroxyphenylalanine

Phosphoenolpyruvate Carboxykinase Is Involved in the Decarboxylation of Aspartate in the Bundle Sheath of Maize [PDF]

open access: yes, 1999
We recently showed that maize (Zea mays L.) leaves contain appreciable amounts of phosphoenolpyruvate carboxykinase (PEPCK; R.P. Walker, R.M. Acheson, L.I. Técsi, R.C. Leegood [1997] Aust J Plant Physiol 24: 459–468).

Synthesis of Hydrophobically and Electrostatically Modified Polyacrylamides and Their Catalytic Effects on the Unimolecular Decarboxylation of 6-Nitrobenzisoxazole-3-carboxylate Anion [PDF]

open access: yes, 1995
A series of hydrophobically and electrostatically modified polyacrylamides (Copol(AM-C12)) has been synthesized by radical-initiated copolymerization of acrylamide with n-dodecylmethyldiallylammonium bromide as the hydrophobe in aqueous solution using ...

A Substrate-induced Biotin Binding Pocket in the Carboxyltransferase Domain of Pyruvate Carboxylase [PDF]

open access: yes, 2013
Biotin-dependent enzymes catalyze carboxyl transfer reactions by efficiently coordinating multiple reactions between spatially distinct active sites. Pyruvate carboxylase (PC), a multifunctional biotin-dependent enzyme, catalyzes the bicarbonate- and ...

Biocatalytic Route to Chiral Precursors of β-Substituted-γ-Amino Acids [PDF]

open access: yes, 2011
In this work, we utilized commercial lipases (from Thermomyces lanuginosa, Rhizopus delemar, and Mucor miehei) as biocatalysts for the efficient synthesis of precursors of β-substituted-γ-amino acids.
