SIMPLE, HIGH-YIELD SYNTHESIS OF UNSYMMETRICALLY FUNCTIONALIZED BISHYDRAZONE AND ALPHA-AZINOHYDRAZONE DERIVATIVES BY REACTION OF ALKOXY AND AMINOCARBONYLAZOALKENES WITH TOSYLHYDRAZONES
Oa. Attanasi et al., SIMPLE, HIGH-YIELD SYNTHESIS OF UNSYMMETRICALLY FUNCTIONALIZED BISHYDRAZONE AND ALPHA-AZINOHYDRAZONE DERIVATIVES BY REACTION OF ALKOXY AND AMINOCARBONYLAZOALKENES WITH TOSYLHYDRAZONES, Synthesis, (4), 1994, pp. 372-374
The reaction of alkoxy- or aminocarbonylazoalkenes with tosylhydrazone
s, in the presence of sodium hydride in a catalytic amount, leads to u
nsymmetrically functionalized bishydrazones that are easily converted
into related alpha-azinohydrazones.
