The condensation of 4-acetyltropolone with various arenecarbaldehydes gave a wide variety of 4-cinnamoyltropolone derivatives in good yield. The same reaction with 2- furaldehyde and cinnamaldehyde also afforded the corresponding 4-substituted tropolones. These products were converted to their oximes (with hydroxylamine hydrochloride), which in turn were hydro genated over 5% Pd/C in acetic acid and then acetylated with acetic ...
