controlled addition of organometallics to optically active β-ketosulfoxide was achieved to furnish both diastereomers of β-hydroxy sulfoxide depending on the selection of organometallic reagents. Trichloromethyltitanium added to (R)-α-(p-tolylsulfinyl)acetophenones to give (RsRc)-β-hydroxy sulfoxides, while (RsSc)-β-hydroxy sulfoxides were obtained by utilizing trimethylaluminum.
