The synthesis of a new chiral pyrrolidine has been performed using 2,3-O-isopropylidene-D-erythronolactol as a suitable starting material.
The title compound, C(14)H(19)NO(5)S, was prepared by nucleophilic addition of the lithium derivative of methyl-phenyl-sulfone to (3S,4R)-3,4-isopropyl-idene-dioxy-pyrroline 1-oxide. There are four mol-ecules in the asymmetric unit. The crystal structure determination confirms the configuration of the chiral centres as 2R,3S,4R. In the crystal, pairs of… (More)
The title compound, C(14)H(17)NO(5)S, was prepared by oxidation of (2R,3S,4R)-2-phenyl-sulfonyl-methyl-1-hy-droxy-3,4-iso-pro-pyl-idene-dioxy-pyrrolidine. Its crystal structure confirms unequivocally its configuration. Two inter-molecular C-H⋯O inter-actions help to establish the packing.
The title compound C(7)H(11)NO(3) was prepared by intra-molecular nucleophilic displacement of 2,3-O-iso-propyl-idene-d-erythronolactol. There are two mol-ecules in the asymmetric unit, which are related by a pseudo-inversion centre. The crystal structure determination confirms unequivocally the configuration of the chiral centres as 3S,4R. In the crystal… (More)
