The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid( cas:560-09-8 ) is researched.Reference of (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid.Liu, Bo; Shekhah, Osama; Arslan, Hasan K.; Liu, Jinxuan; Woell, Christof; Fischer, Roland A. published the article 《Enantiopure Metal-Organic Framework Thin Films: Oriented SURMOF Growth and Enantioselective Adsorption》 about this compound( cas:560-09-8 ) in Angewandte Chemie, International Edition. Keywords: enantiopure metalorganic framework oriented film growth enantioselective adsorption. Let’s learn more about this compound (cas:560-09-8).
The LPE growth of [Zn2[(+)cam]2(dabco)n] [(+)cam = (1R,3S)-(+)-camphoric acid, dabco = 1,4-diazabicyclo[2.2.2]octane] and its enantiomeric form and their application to the direct QCM (quartz crystal microbalance) monitoring of the uptake of a pair of enantiomeric guest mols., namely (2R,5R)-2,5-hexanediol (R-HDO) and (2S,5S)-2,5-hexanediol (S-HDO) from the gas phase under flow conditions are described. As examined by surface X-ray diffraction in out-of-plane and in-plane modes, the SURMOFs (surface-attached MOFs) were grown in (110) and (001) orientations on SAMs of MHDA and PPMT, with MHDA = 16-mercaptohexadecanoic acid; PPMT = (4,(4-pyridyl)phenyl)methanethiol, resp., on Au-coated QCM substrates. The difference of absolute uptake and absorption rate for each of the chosen enantiomeric probe mols. R-HDO and S-HDO is clear, and show significant enantioselectivity.
As far as I know, this compound(560-09-8)Reference of (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
