The preparation of the cyclic sulphamidate of (S)-prolinol has been achieved by reaction with sulphuryl chloride at low temperature. This material has been shown to be susceptible to acid catalysed nucleophilic attack to furnish 2-(N,N-dialkylamino)methyl- and 2-(methoxymethyl)pyrrolidines after hydrolysis of the intermediate sulphamic acid derivatives.
PREPARATION OF PROLINE DERIVED LITHIUM AMIDE BASES AND THEIR USE IN ENANTIOSELECTIVE DEPROTONATION OF MESO EPOXIDES

An alternative method of preparation for a range of proline derived chiral lithium amide bases is described. (S)-2-(Pyrrolidinomethyl) pyrrolidine, prepared by the new route, has been used to deprotonate cis and trans tbutyldimethylisiloxy-3,4-epoxycyclopentane enantioselectively, thus generating chiral cis and trans tbutyldimethylsiloxy-2-cyclopenten-4-ols.The products had higher enantiomeric purity than those produced when the base was prepared by a previously reported method.
