Investigation of dependence of biologicalactivity of 3-organilhydroxymethyl-1,3-oxazacycloalkanes on molecular structure

Research of Kinetic Characteristics of the Process of Decomposition of Zinc Concentrate With Hydrochloric Acid

“…Например, было показано, что первычные амины реагируют с формальдегидом с образованием гексагидросиммтриазина. Проведение реакции в присутствии многоатомных нитроспиртов приводит к образованию 1,3-оксазинов [7]. Реакцией 1,2-или 1,3-аминоалканов с формальдегидом при использовании в качестве спирта N-алкилдиэтаноламинов протекает с образованием 1,1-бис-(1,3-оксазациклоалканметоксиэтил)-алкиламинов.…”

Conformational analysis of 3-methyltetrahydro-1,3-oxazine

“…The interest to non-symmetric 1,3-heterocyclic analogs of cyclohexane, especially to tetrahydro-1,3-oxazines is due to their peculiar structural features [1][2][3][4][5][6][7][8] and valuable pharmacological properties [9][10][11] as well as to their wide application in fine organic synthesis [6,[12][13][14][15][16][17][18][19] and developing of new polymeric materials [20,21]. Dipole moment measurements, NMR studies [1,22,23], and X-ray diffraction analysis [14] have led to conclusion that these compounds predominantly exist in the chair conformation with equatorial (C е ) or axial (C а ) orientation of the N-alkyl group.…”
