Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 23190-16-1, Name is (1R,2S)-(−)-2-Amino-1,2-diphenylethanol, Safety of (1R,2S)-(−)-2-Amino-1,2-diphenylethanol.
(+/-)-anti Head-to-head umbelliferone dimer was resolved into a pair of optically active forms in good yields with high optical purity by a diastereomeric seperation of two diastereomeric diamides obtained by the ring-opening addition reaction with optically pure erythro-2-amino-1,2-diphenylethanol or norephedrine, followed by hydrolysis and relactonization.The absolute configuration of the cyclobutane in (-)589-anti head-to-head umbelliferone dimer was confirmed to be (S,S,S,S) by an X-ray crystallographic analysis of the diamide derived from the (-)589-form by the ring-opening addition reaction with (S)-(-)589-1-(1-naphthyl)ethylamine.The absolute configuration of the cyclobutane in (-)589-anti head-to-head umbelliferone dimer is in agreement with that in (-)589-anti head-to-head coumarin dimer.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Safety of (1R,2S)-(−)-2-Amino-1,2-diphenylethanol. In my other articles, you can also check out more blogs about 23190-16-1
