  • Use of sulfamic acids as resolving agent
    Patent number: 7345202
    Abstract: The invention relates to the use of chiral sulfamic acids as resolving agents, the sulfamic acid having the formula (R1,R2)N—SO3H, wherein: R1 and R2, being the same or different, represent a hydrogen atom or a C1-C30 linear, branched or cyclic (hetero)-aliphatic or (hetero)-aromatic group, provided that R1 and R2 are not both hydrogen and that at least one of the R1 and R2 groups is chiral. Further, methods for resolving enantiomeric mixtures are disclosed.
