Rapid Methylation of Aryl Bromides Using Air‐Stable DABCO‐Bis(Trimethylaluminum) via Nickel Metallaphotoredox Catalysis

Angewandte Chemie, EarlyView.
Herein, we report the use of bis(trimethylaluminum)‐1,4‐diazabicyclo[2.2.2]octane (DABAl‐Me3) as practical source of radicals for the introduction of valuable methyl groups to aryl bromides via a Nickel/metallaphotocatalytic cross coupling strategy.

Recent progress of pyrimidine derivatives for high-performance organic light-emitting devices

, 2018
. Pyrimidine is an electron-deficient azaaromatic compound containing two nitrogen atoms at 1, 3-positions that plays a key role as an organic semiconductor or semiconducting material. Because of the high electron-accepting property induced by C═N double

Phenotypical and Genotypical Expansion of Autosomal‐Dominant KDM1A‐Related Neurodevelopmental Disorder Spectrum: A Case Report

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT KDM1A‐related neurodevelopmental disorder (CPRF, OMIM #616728) is characterized by cleft palate, global developmental delay, and distinct facial gestalt, but phenotypic knowledge of this ultra‐rare autosomal dominant disorder is limited. Here, we report on a 13‐year‐old boy with a novel heterozygous, likely pathogenic germline missense variant

Giant spin canting in the S = 1/2 antiferromagnetic chain [CuPM(NO3)2(H2O)2]n observed by 13C-NMR

, 2005
We present a combined experimental and theoretical study on copper pyrimidine dinitrate [CuPM(NO3)2(H2O)2]n, a one-dimensional S = 1/2 antiferromagnet with alternating local symmetry.

A Transcriptome‐Wide Mendelian Randomization Study in Isolated Human Immune Cells Highlights Risk Genes Involved in Viral Infections and Potential Drug Repurposing Opportunities for Schizophrenia

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Schizophrenia is a neurodevelopmental psychiatric disorder characterized by symptoms of psychosis, thought disorder, and flattened affect. Immune mechanisms are associated with schizophrenia, though the precise nature of this relationship (causal, correlated, consequential) and the mechanisms involved are not fully understood.

Enantiopure Chiral Crystals: A Powerful Tool for Absolute Asymmetric Synthesis

Asian Journal of Organic Chemistry, EarlyView.
This review covers absolute asymmetric syntheses, which allow the preparation of enantiomerically enriched chiral compounds from achiral precursors. By exploiting the crystallization of certain compounds as a conglomerate, enantiopure chiral crystals are spontaneously obtained.

Methyl (6R*,6aR*,12bR*)-2,4-dimethyl-6-(2-methylphenyl)-1,3-dioxo-2,3,4,6a,7,12b-hexahydro-1H,6H-chromeno[4′,3′:4,5]pyrano[2,3-d]pyrimidine-6a-carboxylate

IUCrData, 2017
In the title compound, C24H24N2O6, the mean planes of the pyran rings (A and B) are inclined to one another by 69.2 (1)°, while the aromatic ring (D) of the chromene ring system makes dihedral angles of 63.42 (11) and 66.81 (12)° with the pyrimidine (C ...

Metabolic alterations in human pulmonary artery smooth muscle cells treated with PDGF‐BB

Animal Models and Experimental Medicine, EarlyView.
Metabolic abnormalities are considered to play a key regulatory role in vascular remodeling of pulmonary arterial hypertension. We analyzed the metabolome in the culture supernatants of human pulmonary artery smooth muscle cells (PASMC) during the malignant proliferation phenotype transition via a targeted metabolomics method. Significant and extensive
