Brummel, Beau R.; Lee, Kinsey G.; McMillen, Colin D.; Kolis, Joseph W.; Whitehead, Daniel C. published the article 《One-Pot Absolute Stereochemical Identification of Alcohols via Guanidinium Sulfate Crystallization》. Keywords: alc absolute configuration one pot determination guanidinium sulfate crystallization.They researched the compound: 2-((1R,5S)-6,6-Dimethylbicyclo[3.1.1]hept-2-en-2-yl)ethanol( cas:35836-73-8 ).Reference of 2-((1R,5S)-6,6-Dimethylbicyclo[3.1.1]hept-2-en-2-yl)ethanol. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:35836-73-8) here.
A novel technique for the absolute stereochem. determination of alcs. has been developed that uses crystallization of guanidinium salts of organosulfates. The simple one-pot, two-step process leverages facile formation of guanidinium organosulfate single crystals for the straightforward determination of the absolute stereochem. of enantiopure alcs. by means of X-ray crystallog. The strong hydrogen bonding network drives the stability of the crystal lattice and allows for a diverse range of organic alc. substrates to be analyzed.
