Page/Page column 197-198, (2021/06/26)
Provided herein are compounds, compositions, and methods useful for degrading protein tyrosine phosphatase, e.g., protein tyrosine phosphatase non-receptor type 2 (PTPN2) and/or protein tyrosine phosphatase non-receptor type 1 (PTPN1), and for treating related diseases favorably responsive to PTPN1 or PTPN2 inhibitor treatment, e.g., a cancer 5 or a metabolic disease.
Photoreductive Removal of O-Benzyl Groups from Oxyarene N-Heterocycles Assisted by O-Pyridine-pyridone Tautomerism

Facile photoreductive protocols have been developed to remove benzyl O-protective groups from oxyarene N-heterocycles at positions capable for 2-/4-O-pyridine-2-/4-pyridone tautomerism. Blue light irradiation, a [Ru] or [Ir] photocatalyst, and ascorbic acid in a water-acetonitrile solution debenzylates a variety of aryl N-heterocycles cleanly and selectively. Ascorbic acid has two functions in the reaction. On the one hand, it protonates the N-heterocycles that reduces their reduction potentials notably and on the other hand it acts as a sacrificial reductant. Reduction potentials and free energy barriers calculated at the CPCM-B3LYP/6-31+G? level can predict the reactivities of the studied substrates.
Herbicidal 2,6-substituted pyridines

, (2008/06/13)
A herbicidal composition which comprises at least one carrier and, as active ingredient, a compound of the general formula STR1 in which each of n and m independently is 0 or 1; each of Ar1 and Ar2 independently is an aryl group, at least one of Ar1 and Ar2 being substituted by one or more of the same or different substituents selected from halogen atoms, alkyl groups, alkoxy groups, haloalkyl groups and haloalkoxy groups; and R1 is hydrogen, or an alkyl, alkylthio or haloalkyl group having from 1 to 4 carbon atoms, and R2 is hydrogen or a halogen atom provided that at least one of R1 and R2 represents a hydrogen atom. Certain compounds of formula I are novel.
