In Vitro Anticancer Activity and Mechanism of Action of an Aziridinyl Galactopyranoside

open access: yesBiomedicines, 2021
We recently screened a series of new aziridines β-D-galactopyranoside derivatives for selective anticancer activity and identified 2-methyl-2,3-[N-(4-methylbenzenesulfonyl)imino]propyl 2,3-di-O-benzyl-4,6-O-(S)-benzylidene-β-D-galactopyranoside (AzGalp ...

N-(1-Phenylethyl)aziridine-2-carboxylate esters in the synthesis of biologically relevant compounds

open access: yesBeilstein Journal of Organic Chemistry, 2019
Since Garner’s aldehyde has several drawbacks, first of all is prone to racemization, alternative three-carbon chirons would be of great value in enantioselective syntheses of natural compounds and/or drugs. This review article summarizes applications of

Aziridine Ring Opening as Regio- and Stereoselective Access to C-Glycosyl-Aminoethyl Sulfide Derivatives

open access: yesMolecules, 2022
A short synthetic route to stereoselective access to C-glycosyl-aminoethyl sulfide derivatives has been developed through the reaction of tributhyltin derivatives of glycals with aziridinecarboaldehyde and the regioselective ring opening of a chiral ...

Aziridinierung eines einzelnen Kohlenstoffatoms in Alkenen mittels Energietransferkatalyse

open access: yesAngewandte Chemie, EarlyView.
Im Gegensatz zur traditionellen Alken‐Aziridinierung über (formalen) Nitren‐Transfer berichten wir hier über eine Strategie zur intermolekularen Aziridinierung eines einzelnen Alken‐Kohlenstoffatoms bei zusätzlicher Funktionalisierung der anderen Position. Durch Energietransfer‐ (EnT‐)Katalyse werden Alkenylboronate und ‐silane in reaktive Intermediate
