The application of N,N-dimethylacetamide or 1-methyl-2-pyrrolidone as solvent clearly accelerated the sulfamoylation reaction of a hydroxyl group compared with the solvents used so far. The target sulfamates were obtained in the highest yield without a base. It became clear that 2 equiv. of sulfamoyl chloride to the starting material was sufficient to complete the reaction. It was confirmed that this condition could be applied to extensive hydroxyl groups, (C) 2000 Elsevier Science Ltd. All rights reserved.

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.
