Abstract

Combination of the regioselective hydrogenation of the prochiral diketone 1,2-indanedione with chemoenzymatic dynamic kinetic resolution of the resulting rac-2-hydroxy-1-indanone was investigated. A new simple to operate, one-pot reaction sequence provides the valuable building block (R)-2-acetoxy-1-indanone in moderate enantiopurity (86–92% ee) and a competitive isolated yield (39%) compared with a traditional isolated batch reaction approach.
