Propargyl Anthranilate Derivatives and Their Application in the Synthesis of Rings Containing 1,2,3-Triazolo Motifs
Autor: Ludmila Hradilová, Pavel Hradil, Antonin Lycka, Jan Hlaváč, Martin Grepl
Publikováno v: Journal of Heterocyclic Chemistry. 50:528-533
Propargyl anthranilate, a simple and less studied molecule with several reactive sites, is widely applicable in organic synthesis. An optimized synthesis of this compound and its derivatives and the preparation of azide derivatives are described. The

Publikováno v: ResearcherID
Scopus-Elsevier
As known, some derivatives of quinolin-4(1H)-one possess interesting biological properties. The biological and cytostactic activity of 2-substituted 3-hydroxyquinolin-4(1H)-ones has not been reported yet. In this paper the synthesis of a series of ch

15N NMR Spectroscopy in Structural Analysis
Autor: Antonin Lycka, Radek Marek
Publikováno v: Current Organic Chemistry. 6:35-66
The implementation of both the directly and the inversely detected 15N NMR techniques at the natural abundance level of the 15N isotope is demonstrated for a diverse array of structural problems in organic chemistry. Following the application of 15N
