Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 82954-65-2, is researched, SMILESS is NC[C@@H]1OC(C)(C)OC1, Molecular C6H13NO2Journal, Macromolecules called Macromolecular stereochemistry: the effect of pendant group structure on the axial dimension of polyisocyanates, Author is Green, Mark M.; Gross, Richard A.; Crosby, Charles III; Schilling, Frederic C., the main research direction is axial dimension polyisocyanate optical activity; polydimethyldioxolanemethylene isocyanate persistence length.Quality Control of (S)-(2,2-dimethyl-[1,3]-dioxolan-4-yl)-methylamine.
Chains of optically active poly[(S)-2,2-dimethyl-1,3-dioxolane-4-methylene isocyanate] (I) [107797-37-5] were more extended than those of its racemic isomer (II) [96743-47-4] and poly(n-Bu isocyanate) (III) as determined by light scattering measurements. I exhibited a CD spectrum similar to that of poly(2-methylbutyl isocyanate). The UV spectra of I and II were differed from those of III. The results were consistent with helix reversal contribution to the wormlike behavior of polyisocyanates.
