It was decided in this problem to prepare 2-phenyl-2,1,3-triazole-4-carboxaldehyde (III) as a starting material by the method suggested by Hann and Hudson and run a number of typical aldehyde reactions with it. The preparation of (III) involved: (1) The hydrolysis of sucrose to form glucose and fructose; (2) conversion of these two sugars to D-glucose phenylosazone (I), by reaction with phenylhydrazine; (3) transformation of (I) to D-glucose phenylosotraizole (II), by the action of hot aqueous copper sulfate; and (4) oxidation of the side chain from (II) with sodium periodate, forming (III).
The reactions selected were: (1) the Grignard reaction; (2) the Perkin reaction; (3) condensation of the aldehyde with a diamine to yield an imidazolidine; (4) oxidation to the acid and condensation of this acid with a diamine to yield an imidazoline; (5) condensation with acetone; and (6) a crossed Cannizzaro reaction, yielding primarily 2-phenyl-2,1,3-triazol-4-yl-carbinol.
