Synthetic Processes toward Nitriles without the Use of Cyanide: A Biocatalytic Concept Based on Dehydration of Aldoximes in Water

While belonging to the most fundamental functional groups, nitriles represent a class of compound that still raises challenges in terms of an efficient, cost-effective, general and, at the same time, sustainable way for their synthesis. Complementing existing chemical routes, recently a cyanide-free enzymatic process technology based on the use of an aldoxime dehydratase (Oxd) as a biocatalyst component has been developed and successfully applied for the synthesis of a range of nitrile products. In these biotransformations, the Oxd enzymes catalyze the dehydration of aldoximes as readily available substrates to the nitrile products. Herein, these developments with such enzymes are summarized, with a strong focus on synthetic applications. It is demonstrated that this biocatalytic technology has the potential to cross the bridge between the production of fine chemicals and pharmaceuticals, on one hand, and bulk and commodity chemicals, on the other.

Studies on the pyrrolinone metabolites derived from the tobacco alkaloid 1-methyl-2-(3-pyridinyl)pyrrole (beta-nicotyrine)

Previous studies have established that the tobacco alkaloid 1-methyl-2-(3-pyridyl)pyrrole (beta-nicotyrine) is biotransformed by rabbit lung and liver microsomal preparations to an equilibrium mixture of the corresponding 3- and 4-pyrrolin-2-ones. Autoxidation of these pyrrolin-2-ones generates the chemically stable 5-hydroxy-5-(3-pyridinyl)-3-pyrrolin-2-one. This paper summarizes efforts to document more completely the pathway leading to this hydroxy-pyrrolinone. Chemical and spectroscopic evidence implicates the 2-hydroxy-1-methyl-5-(3-pyridinyl)pyrrole (2-hydroxy-beta-nicotyrine) as the key intermediate in this reaction pathway. Of potential toxicological interest is the detection of radical species derived from the autoxidation of this compound.

5-Acetoxy-1-acetyl-3-pyrrolin-2-one

The chiral title compound, C8H9NO4, crystallizes in the non-centrosymmetric space group P2(1)2(1)2(1), but in the absence of an atom with significant anomalous dispersion, the absolute configuration could not be determined. The H atoms in both methyl groups are eclipsed with respect to the C=O bond. The structure features weak C-H center dot center dot center dot O interactions that link the molecules into a three-dimensional network.

The requirement for cobalt in vitamin B-12: A paradigm for protein metalation

Vitamin B-12, cobalamin, is a cobalt-containing ring-contracted modified tetrapyrrole that represents one of the most complex small molecules made by nature. In prokaryotes it is utilised as a cofactor, coenzyme, light sensor and gene regulator yet has a restricted role in assisting only two enzymes within specific eukaryotes including mammals. This deployment disparity is reflected in another unique attribute of vitamin B-12 in that its biosynthesis is limited to only certain prokaryotes, with synthesisers pivotal in establishing mutualistic microbial communities. The core component of cobalamin is the corrin macrocycle that acts as the main ligand for the cobalt. Within this review we investigate why cobalt is paired specifically with the corrin ring, how cobalt is inserted during the biosynthetic process, how cobalt is made available within the cell and explore the cellular control of cobalt and cobalamin levels. The partitioning of cobalt for cobalamin biosynthesis exemplifies how cells assist metalation.

Synthesis and evaluation of the anti-proliferative activity of diaryl-3-pyrrolin-2-ones and fused analogs

Analogs containing a central 3-pyrrolin-2-one core with different methoxyphenyl and/or indole substituents were prepared and tested for anti-proliferative activity in U-937 cells. The most efficacious analogs were non-rigid, (non-fused) contained methoxyaryl groups located at the 4-position, and contained either methoxyaryl or indole groups located at the 3-position. Both the number of methoxy groups contained in the substituents and the particular location of the indole rings with respect to the lactam carbonyl had significant affects on anti-proliferative activity. This work provides a framework to better understand structure-activity relationships for inducing anti-proliferative activity in diaryl heterocyclic scaffolds. (C) 2016 Elsevier Ltd.
