In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Enantioselective transport of amino acid through supported chiral liquid membranes, published in 1993-12-02, which mentions a compound: 35836-73-8, Name is 2-((1R,5S)-6,6-Dimethylbicyclo[3.1.1]hept-2-en-2-yl)ethanol, Molecular C11H18O, Product Details of 35836-73-8.
Two chiral alcs., nopol and (2S)-(-)-methyl-1-butanol, immobilized in the pores of a polyethylene film, were used for the enantioselective transport of amino acid hydrochlorides. The degree of stereoselectivity of the permeation process varied from 0.39 to 1.52 depending on both the type of the chiral membrane phase and the properties of the amino acid. Evaluation of the ability of the membrane to sep. stereoisomers was performed by a step-by-step anal. procedure, considering the effect of amino acids, hydrophobicity, polarity and degree of chirality. For the purpose of this paper, the chirality measure was introduced. The enantioselectivity was affected mainly by the degree of chirality, and the nopol membrane was the more efficient one.
As far as I know, this compound(35836-73-8)Product Details of 35836-73-8 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
