First example of carbonyl condensation of cyclopentadienone hydrazone giving mixed azine and its subsequentendo-dimerization into the tricyclo[5.2.1.02.6]decadiene system
摘要:
The monomeric hydrazone of cyclopenta-2,4-dienone (cyclone) undergoes condensation with 2-hydroxy-3-methoxybenzaldehyde to yield the corresponding mixed azine, which spontaneously dimerizes to 4, 10-bis(2-hydroxy-3-methoxybenzalazino)tricyclo[5.2.1.0(2.6)]deca-3,8-diene.
