Solutions of (4j in organic solvents display an intensive blue fluorescence and in aqueous mineral acids a blue-green fluorescence. In the N M R spectrum (CDC13) a singlet occurs at T = 0.87, which is ascribed to the protons H-1 and H-3 (the neighboring protons to the ring nitrogen); the
We have studied the fluoroalkylation of the glucal 1 and the galactal 4 with dibromodifluoromethane via the 2-C-bromodifluoromethyl-substituted glycosyl bromides 2 and 5, respectively, followed by glycosylation to the methyl Γ-D-gly-
The structure of product (8) follows from its cleavage by acid to cyclohexanone (2,4-dinitrophenylhydrazone, m.p. 162 "C) and 4-phenylsemicarbazide (benzylidene derivative, m. p. and mixed n1.p. 180Β°C).
