STEREOSELECTIVE RADICAL-MEDIATED CYCLIZATION OF NOREPHEDRINE DERIVED ALPHA-IODOAMIDES - EXPERIMENTS AND TS-MODELING

, 1991
Radical-mediated cyclization of norephedrine derived alpha-iodoamides 1 was found to be highly stereoselective (greater-than-or-equal-to 97:3) favouring diastereoisomer 2.

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Metabolism of cathinone to (−)-norephedrine and (−)-norpseudoephedrine

, 1986
S-(−)-Cathinone (S-(−)-α-aminopropiophenone) is the major active principle of khat leaves (Catha edulis), which are widely used in East Africa and the Arab peninsula as an amphetamine-like stimulant.

Effect of Intramolecular Hydrogen Bonds on the Binding Efficiency of Compounds Containing Aminoalcohol‐Based Subunits in Combination with Heterocyclic Groups

European Journal of Organic Chemistry, Volume 29, Issue 29, 7 August 2026.
This study broadens our understanding of the role of intramolecular interactions in molecular recognition and highlights the importance of considering their formation when designing artificial receptors, new drugs, and related systems. Aminoalcohols represent an important class of compounds and serve as building blocks for numerous biologically active ...

Health, Social and Recidivism Outcomes Among People Who Have Been Incarcerated in New South Wales, Australia: Study Protocol and Cohort Profile for the Prison Outcomes STudy (POST)

Drug and Alcohol Review, Volume 45, Issue 5, July 2026.
ABSTRACT Introduction We have been funded to examine post‐incarceration health and social outcomes for all people incarcerated in New South Wales, Australia, 2000–2022; assess treatment and services for drug dependence and serious mental illness; and project the impact of expanding intervention coverage. We will use a linked cohort, the Prison Outcomes

Cathine and norephedrine, both phenylpropanolamines, accelerate capacitation and then inhibit spontaneous acrosome loss

, 2005
BACKGROUND: Cathinone, released when Catha edulis leaves (khat) are chewed, has euphoric, stimulatory properties. It is metabolized to the phenylpropanollamines (PPAs) cathine and norephedrine.

Metabolic N- and α-C-oxidation of norephedrine by rabbit liver microsomal fractions and synthesis of the metabolic products

, 1974
The products of metabolism of norephedrine by 10 000 g fractions of rabbit liver microsomes have been shown to be norephedrine hydroxylamine, l-hydroxy-2-oxo-l-phenylpropane oxime, 1-hydroxy-2-oxo-1-phenylpropane, 1,2-dihydroxy-l-phenylpropane (erythro).

Combination of a UPO‐Based Epoxidation With a Subsequent Ring‐Opening Reaction for the Synthesis of Amino Alcohols

ChemBioChem, Volume 27, Issue 5, 13 March 2026.
The synthesis of aromatic amino alcohols via a combination of an unspecific peroxygenase‐catalysed reaction, oxyfunctionalization, and addition of selected nucleophiles and electrophiles in a highly atom‐efficient manner was investigated. This study presents the design to aim for an atom‐efficient chemo‐enzymatic synthesis route towards aromatic amino ...
