Diversity-Oriented Synthesis Based on the DPPP-Catalyzed Mixed Double-Michael Reactions of Electron-Deficient Acetylenes and β-Amino Alcohols

open access: yesMolecules, 2011
In this study, we prepared oxizolidines through 1,3-bis(diphenylphosphino)-propane (DPPP)–catalyzed mixed double-Michael reactions of b-amino alcohols with electron-deficient acetylenes.

2-Oxiranyl-pyridines: Synthesis and Regioselective Epoxide Ring Openings with Chiral Amines as a Route to Chiral Ligands

open access: yesHeteroatom Chemistry, 2019
New epoxides, derivatives of pyridine, 2,2′-bipyridine, and 1,10-phenanthroline, were synthesized from the respective α-methylazaarenes. The obtained racemic 2-oxiranyl-azaarenes along with styrene oxide and trans-stilbene oxide were submitted to the ...

Tunable synthesis of furfurylamines or β-amino alcohols via Ru-catalyzed N–H functionalization using biomass-derived polyols

open access: yesGreen Synthesis and Catalysis, 2022
We report the highly efficient conversion of readily available biomass-derived polyols with amines to valuable furfurylamines or β-amino alcohols compounds using ruthenium catalysis.

Asymmetric Palladium-Catalysed Intramolecular Wacker-Type Cyclisations of Unsaturated Alcohols and Amino Alcohols

open access: yesMolecules, 2013
The palladium (II)-catalysed reactions of alkenols and aminoalkenols such as oxycarbonylations or bicyclisations are powerful methods for the construction of oxygen and nitrogen-containing heterocyclic compounds. This review highlights recent progress in

Comparative GC–MS based nutrients profiling of less explored legume seeds of Melilotus, Medicago, Trifolium, and Ononis analysed using chemometric tools

open access: yesScientific Reports, 2023
Exploring novel sources of plant protein for nutrition of both humans and animals is motivated mainly by its growing demand worldwide, besides identifying healthy alternatives for animal protein. The present study evaluates metabolome diversity within 15

Alcohol, Amino Acids, and Albumin Synthesis

open access: yesGastroenterology, 1974
The isolated perfused rabbit liver was used to compare the acute effects of alcohol and amino acids on albumin synthesis, polysomal aggregation, and RNA turnover. The perfusion solutions were modified to contain test amino acids in a final concentration of 10 mM, and/or alcohol was added and maintained at 220 mg per 100 ml.

Short and Efficient Synthesis of Optically Active N-Tosyl Aziridines from 2-Amino Alcohols

open access: yesMolecules, 2002
Two alternative and complementary one-pot procedures for the direct transformation of 2-amino alcohols to N-tosyl aziridines are presented. The unsubstituted parent compound and its less hindered homologues can be obtained in high yields by tosylation ...

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...
