Abstract

A novel chiral C2-symmetric spiro diol, 3,3,3′,3′-tetramethyl-1,1′-spirobiindane-7,7′-diol (TMSIOL), was conveniently prepared via practical seven-step route from Bisphenol A in 45.1% overall yield. l-Menthyl chloroformate is used as optical resolving agent for the separation of the two enantiomers of TMSIOL.
