Improved Synthesis of a Sub-Nanomolar Vinyl Phosphonate Inhibitor of Dehydroquinate Synthase [PDF]

Molecules
In connection with a project aiming at the evaluation of antimicrobial agents, a vinyl phosphonate inhibitor of 3-dehydroquinate synthase was needed. As a result, the original five-step synthesis was reinvestigated resulting in a four-step process with ...

Synthesis of Functionalized Diethyl(pyrrolidin-2-yl)phosphonate and Diethyl(5-oxopyrrolidin-2-yl)phosphonate

Molecules, 2021
Short and efficient syntheses of functionalized (pyrrolidin-2-yl)phosphonate and (5-oxopyrrolidin-2-yl)phosphonate have been developed. The synthetic strategy involved the diastereospecific 1,3-dipolar cycloaddition of N-benzyl-C-(diethoxyphosphoryl ...

Influence of Phosphorus Structures and Their Oxidation States on Flame-Retardant Properties of Polyhydroxyurethanes

Molecules, 2023
This article focuses on the synthesis of polyhydroxyurethane (PHU) materials containing novel phosphorus flame retardants (FR). Four different phosphorus compounds were grafted onto cyclic carbonate: 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide ...

The facilitating role of phycospheric heterotrophic bacteria in cyanobacterial phosphonate availability and Microcystis bloom maintenance

Microbiome, 2023
Background Phosphonates are the main components in the global phosphorus redox cycle. Little is known about phosphonate metabolism in freshwater ecosystems, although rapid consumption of phosphonates has been observed frequently.

Diethyl [(2,5-diiodo-4-methylphenyl)methyl]phosphonate

IUCrData, 2021
The title compound, C12H17I2O3P, was prepared in three steps from p-xylene. Heterodimers between nearly identical molecules are connected via three hydrogen bonds from benzylic and ester methylene groups to phosphonate. The dimers form chains along the a-

A Novel Biosynthetic Gene Cluster Across the Pantoea Species Complex Is Important for Pathogenicity in Onion

Molecular Plant-Microbe Interactions, 2023
Onion center rot is caused by at least four species of genus Pantoea (P. ananatis, P. agglomerans, P. allii, and P. stewartii subsp. indologenes). Critical onion pathogenicity determinants for P.

Room-Temperature Alternative to the Arbuzov Reaction: The Reductive Deoxygenation of Acyl Phosphonates [PDF]

, 2010
The reductive deoxygenation of acyl phosphonates using a Wolff−Kishner-like sequence is described. This transformation allows direct access to alkyl phosphonates from acyl phosphonates at room temperature. The method can be combined with acyl phosphonate
