(2S,3S,4R,5S,6R)-3-Acetamido-6-(acetoxymethyl)tetrahydro-2H-pyran-2,4,5-triyl triacetate (cas: 6730-10-5) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.SDS of cas: 6730-10-5

N-Acyl derivatives of 2-acylamino-2-deoxyhexoses. Nuclear magnetic resonance spectra and conformations was written by Inch, Thomas D.;Plimmer, Jack R.;Fletcher, Hewitt G. Jr.. And the article was included in Journal of Organic Chemistry in 1966.SDS of cas: 6730-10-5 This article mentions the following:

The N.M.R. spectra of some 1,3,4,6-tetra-O-acetyl-2-(N-acylacylamino)2-deoxyhexoses and of some 2-acetamido-1,3,4,6-tetra-O-acetyl-2-deoxyhexoses of the D-glucose, D-galactose, and D-mannose series have been studied. In contrast to the spectra of the second class of compounds, those of the first class are readily analyzed. The coupling constants for representatives of the D-glucose and D-galactose series clearly show these compounds to exist in the normal chair conformation. In N-acylacylamino derivatives of the D-glucose series, the signal from the axial proton at C-1 occurs at lower field than the signal for the equatorial C-1 proton, a reversal of the normal situation which has not hitherto been observed at C-1. The conformational implications of the N.M.R. spectra are discussed. In the experiment, the researchers used many compounds, for example, (2S,3S,4R,5S,6R)-3-Acetamido-6-(acetoxymethyl)tetrahydro-2H-pyran-2,4,5-triyl triacetate (cas: 6730-10-5SDS of cas: 6730-10-5).
