Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, the author is Fukui, Hiroki and a compound is mentioned, 4254-15-3, (S)-Propane-1,2-diol, introducing its new discovery. 4254-15-3

NMR determination of the absolute configuration of chiral 1,2- and 1,3-diols

Each of the chiral 1,2- and 1,3-diols examined was derivatized exclusively to a single diastereomeric acetal by the use of a new axially chiral reagent, 2?-methoxy-1,1?-binaphthalene-8-carbaldehyde (MBC). The absolute configuration of the original 1,2- and 1,3-diols was determined by the NOE correlation between the proton signals of the reagent moiety and those of the diol moiety in the acetals.
