(2R,3S,4R)-3,4-Isopropylidenedioxy-2-(phenylsulfonylmethyl)pyrrolidin-1-ol
Abstract
The title compound, C14H19NO5S, was prepared by nucleophilic addition of the lithium derivative of methylphenylsulfone to (3S,4R)-3,4-isopropylidenedioxypyrroline 1-oxide. There are four molecules in the asymmetric unit. The crystal structure determination confirms the configuration of the chiral centres as 2R,3S,4R. In the crystal, pairs of O—H...N hydrogen bonds link the molecules into dimers.
