A concise, enantioselective synthesis of the potent aldose reductaseinhibitor ranirestat (1) is reported. The synthesis was accomplished employing inexpensive, commercially available starting materials. A palladium-catalyzed asymmetric allylic alkylation (Pd-AAA) of malonate 4 was utilized as a key transformation to construct the tetrasubstituted chiral center in the target.
The invention relates to macrocyclic picolinamides of Formula I and their use as fungicides.
