| Hazard Information | Back Directory | [Uses]
(R)-(+)-1,1,2-triphenyl-1,2-ethanediol can be used to derivatize chiral monoesters via stereoselective aldol addition; forming O-silyl orthoesters and cyclic phosphonates. | [Preparation]
(R)-1,1,2-triphenylethane-1,2-diol [(R)-(1)] is easily available from commercial (R)-Mandelic Acid, which is first esterified to give methyl mandelate and then treated with Phenylmagnesium Bromide (3.5 equiv). In an analogous way, (S)-(1) is accessible from (S)-mandelic acid, which is also commercially available (eq 1).
