General description
(S)-(-)-1-Phenylethanol can be prepared from acetophenone via enantioselective bioreduction in the presence of Rhizopus arrhizus as a biocatalyst.
Application
(S)-(-)-1-Phenylethanol can be used as:
- A starting material to prepare (1S,3R,4S)-1-methyl-3,4-diphenyl-3,4-dihydro-1H-isochromene-3,4-diol (a cyclic hemiacetal) by reacting with benzil via dilithiation reaction.
- A chiral solvent in the symmetric synthesis of substituted spiroundecenetriones via amino acid-catalyzed domino Knoevenagel/Diels-Alder reactions.
