1-Aryl-4-carboxy-5-methyl-1,2,3-triazoles were prepared by the condensation of aryl azides with ethyl acetoacetate. The structures of these compounds were characterized by MS, IR and 1H and 13C NMR spectroscopy. The measured and calculated 13C chemical shifts of the aromatic carbons were compared.
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 correlati
