Synthesis and Reactions of 3-Carboxytropolone. Conversion to Heterocycle-fused Troponoid Compounds
The haloform reaction of 3-acetyltropolone (1) afforded 3-carboxytropolone (2) which was treated with diazomethane to give 2-methoxy-3-methoycarbonyltropone (3a) and 2-methoxy-7-methoxycarbonyltropone (3b).The tropolone 2 reacted with hydrazine to afford

VINYLIC SUBSTITUTION ON TROPONOID CATALYZED BY PALLADIUM COMPLEXES, AND FORMATION OF NEW C-Pd ?-COMPLEXES OF TROPONOID
The reaction of 3-, 4- and 5-halotropolones with olefins catalyzed by palladium(0) complex gave 3-, 4- and 5-(substituated vinyl)tropolones respectively.Similarly, 2-chlorotropone gave 2-styryltropones.Some tropolonyl- and troponylpalladium-?-complexes we
