The synthesis and biological activity of the novel diastereoisomers of 2-benzyl-2, 3-dihydro- 2-(1H-inden-2-yl)-1H-inden-1-ol is reported. The 2, 2-coupled indane dimers were synthesised by coupling of the silyl enol ether of 1-indanone with the dimethyl ketal of 2- indanone. The coupled product was directly alkylated to give the racemic ketone which was reduced to the diastereoisomeric alcohols. The alcohols were separated and their relative ...
