Investigation on the reactivity of α-azidochalcones with carboxylic acids: Formation of α-amido-1,3-diketones and highly substituted 2-(trifluoromethyl)oxazoles

open access: yesBeilstein Journal of Organic Chemistry, 2015
The reaction of α-azidochalcones with carboxylic acids has been investigated resulting in the formation of α-amido-1,3-diketones under microwave irradiation via in situ formation of 2H-azirine intermediates.

Manganese(I)-Catalyzed Highly Enantioselective Synthesis of Aziridine Phosphines [PDF]

open access: yes
Herein, we present the first catalytic asymmetric nucleophilic addition of diarylphosphines to 2H-azirines, facilitated by a chiral Mn(I) complex. This method not only provides access to novel class of derivatives of the aziridine core-a structural motif

Intermolecular alkyl radical addition to methyl 2-(2,6-dichlorophenyl)-2H-azirine-3-carboxylate [PDF]

open access: yes, 2003
The 2H-azirine 1 acts as an effective radical acceptor for secondary and tertiary alkyl iodides mediated by triethylborane. The addition proceeds with high regio- and diastereo-selectivity.The present work has been supported by Fundação para a Ciência e ...

Enumeration of saturated and unsaturated substituted N-heterocycles

open access: yes, 2023
Mathematical and computational approaches in chemistry and biochemistry fill a gap in respect to the analysis of the physicochemical features of compounds and their functionality and provide an overview of known as well as yet unknown, but hypothetically

Multistep flow synthesis of vinyl azides and their use in the copper-catalyzed huisgen-type cycloaddition under inductive-heating conditions [PDF]

open access: yes, 2011
The multistep flow synthesis of vinyl azides and their application in the synthesis of vinyltriazoles is reported. The synthesis relies on a stable polymer-bound equivalent of iodine azide that serves to carry out 1,2-functionalization of alkenes in a ...
