(±)-cis,cis-2,2′-spirobiindane-1,1′-diol (1) is synthesized stereoselectively in four steps beginning with 1-indanone in 68% overall yield. An improved resolution of diol 1 is described by preparing and separating diastereomeric mono-esters of 1 using (2S)-O-(tert-butyldimethylsilyl)mandeloyl chloride (10).
