crystalline isotopically labeled (1R)-menthyl (1S,2S)- (+)-2-phenylcyclopropanecarboxyates of better than 99% enantiomeric excess has provided multi-gram quantities of the corresponding chiral phenylcyclopropanes. The key transformation involved a bis(1,3-bis(diphenylphosphino)propane)rho- dium chloride that catalyzed a highly stereoselective decarbonylation of a trans-2-phenylcyclopropanecarboxaldehyde.
