Preparation of 2- and 6-pyridones of N1-methylnicotinamide.
In the course of experiments designed to elucidate the structure of reduced diphosphopyridine nucleotide (DPNH) (12), it became necessary to prepare the 2and 6-pyridones of iV-methylnicotinamidel by oxidation of the latter. Huff (5) has described the preparation of N’-methyl-6-pyridone-3-carboxylic acid by alkaline ferricyanide oxidation of either trigonelline or N’-methylnicotinamide. The acid...
متن کاملN1,N1,N2,N2-Tetramethyl-N1,N2-bis(sulfo)ethane-1,2-diaminium chloride as a highly efficient catalyst for synthesis of some nitrogen- and oxygen-containing heterocyclic compounds
In this research, a Brønsted acidic ionic liquid namely N1,N1,N2,N2-tetramethyl-N1,N2-bis(sulfo)ethane-1,2-diaminium chloride {[TMBSED][Cl]2} was employed as a highly efficient catalyst for the solvent-free production of some nitrogen- and oxygen-containing heterocyclic compounds including: (i) polyhydroquinolines (from arylaldehydes, dimedone, β-ketoesters and ammonium acetate), (ii) 3,4-dihyd...
متن کاملN1 – IUBMB 50th Anniversary Symposium: Protein Structure and Function N1-001 Molecular biology of mammalian prions
Transmissible spongiform encephalopathies (TSE) are fatal neurodegenerative diseases of humans and animals. The underlying infectious agent, the prion, accumulates not only in the central nervous system (CNS) but also in secondary lymphoid organs. I will revisit the role of the immune system in peripheral prion pathogenesis, while focusing on the mechanisms by which extraneural and extralymphat...
متن کاملFunctional neural dynamics underlying auditory event-related N1 and N1 suppression response.
Presenting tone triplets of identical stimuli preceded by silent intervals of 30 s produces a series of three N1 averaged event-related potentials (ERPs), the first being of greater amplitude (non-suppressed N1) than the second and third ones (suppressed N1). Maximal statistically independent components (ICs) of single-trial multi-electrode scalp EEG responses to triplets were obtained by ICA a...
متن کاملHeritability of anterior and posterior visual N1.
Previous studies have reported that individual variation in N1 amplitude is related to attentional problems and alcoholism. Using data from 651 twins and siblings from 292 families we examined whether variation in N1 amplitude and latency can be explained by genetic factors. In half of the subjects the age centered around 26 (young adult cohort), in the other half the age centered around 49 (mi...
