Abstract

The reactions of sodium salt of 2-methoxy-1-azaazulene-3-carboxaldehyde tosylhydrazone with styrenes gave 3,8-cyclohexeno-2-methoxy-1-azaazulenes and 3-cyclopropyl-2-methoxy-1-azaazulenes. The formers were afforded through the diazo compound generated from the tosylhydrazone and the latters were yielded via the carbene derived from the diazo compound. The reactions with stilbenes gave the corresponding cyclopropane derivatives. The similar reactions with sodium salt of azulene-1-carboxaldehyde tosylhydrazone gave the analogous result.
