THEORETICAL AND CHEMOMETRIC STUDY OF SUBSTITUTED OXAZINES
(Sociedad Chilena de Química, 2005)
Theoretical and chemometric study of substituted oxazines
(Soc Chilena QuimicaConcepcionChile, 2005)
Microwave-Assisted Synthesis of 2-Aryl-2-oxazolines, 5,6-Dihydro-4H-1,3-oxazines, and 4,5,6,7-Tetrahydro-1,3-oxazepines
(American Chemical Society, 2016-12)
The first general procedure for the synthesis of 5- to 7-membered cyclic iminoethers by microwave-assisted cyclization of ω-amido alcohols promoted by polyphosphoric acid (PPA) esters is presented. 2-Aryl-2-oxazolines and ...
Oxazine Ring-Related Vibrational Modes of Benzoxazine Monomers Using Fully Aromatically Substituted, Deuterated, 15N Isotope Exchanged, and Oxazine-Ring-Substituted Compounds and Theoretical Calculations
(American Chemical Society, 2017-08)
Polymerization of benzoxazine resins is indicated by the disappearance of a 960-900 cm-1 band in infrared spectroscopy (IR). Historically, this band was assigned to the C-H out-of-plane bending of the benzene to which the ...
THE EFFECT OF C2 AND C5 SUBSTITUTIONS ON THE NITROGEN LONE PAIR INVERSION IN 1,3-OXAZINES"
(Sociedad Chilena de Química, 2009)
Cyclohexene-fused 1,3-oxazines with selective antibacterial and antiparasitic action and low cytotoxic effects
(Pergamon-Elsevier Science Ltd, 2017-10)
Oxazine derivatives, a class of heterocyclic compounds, exhibit a variety of biological properties, such as anticonvulsant and antitumor activities. In this study, we evaluated the effect of two cyclohexene-fused 1,3-oxazines ...
Synthesis and Photophysical Properties of 1,4-Dihydro-2 H,5H-chromeno[4,3-D][1,3]oxazin-5-ones, and Derivatives Containing Tethered 1,2,3-Triazoles, from 4-Aminocoumarins
(Georg Thieme Verlag Kg, 2019-04)
A facile protocol for the unprecedented one-pot H 2 SO 4 -mediated hydroxymethylation/cyclative N, O -acetalization of 4-aminocoumarins to 1,4-dihydro-2 H,5 H -chromeno[4,3- d ][1,3]oxazin-5-ones, in moderate to good yields, ...
