Syntheses of mycophenolic acid and its analogs by palladium methodology
Syntheses of mycophenolic acid (MPA, 1) and its analogs were carried out using palladium-catalyzed Heck carbonylation and olefination. Thus, the reaction of 2-bromo-3,5-dimethoxybenzyl alcohol (4) in toluene under carbon monoxide at 180 C in the presence of palladium catalyst using sodium carbonate as a base gave 5,7-dimethoxyphthalide (5) in 88% yield. The phthalide 7 was converted to 6-iodo-5,7-dimethoxy-4-methylphthalide (8). Reaction of aromatic iodide 8 with isoprene and dimethyl malonate in the presence of palladium(0) catalyst gave the three component coupling product 9, which was converted into 1 in three steps. 4-NorMPA (16) and 4-homoMPA (22) were synthesized similarly.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of Tris(dibenzylideneacetone)dipalladium-chloroform, you can also check out more blogs about52522-40-4
