A safe and practical synthetic method for preparing axially chiral di-Ph dicarboxylates using Pd-catalyzed external-CO-free carbonylation with Ph formate as a CO surrogate was developed. Optimized conditions consisted of axially chiral [1,1′-binaphthalene]-2,2′-diyl ditriflate and its congeners, each easily prepared from com. available enantiomerically pure diols, Pd(OAc)2, 1,3-bis(diphenylphosphino)propane, ethyldiisopropylamine, and no solvent. To demonstrate the potential utility of these products, this method was conducted on gram-scale and the Ph ester products were converted to other useful compounds, and both processes were carried out without difficulty.
