In this study, several novel sulfamides were synthesized and evaluated for their acetylcholineesterase (AChE) and human carbonicanhydrase I, and II isoenzymes (hCA I and II) inhibition profiles. Reductive amination of methoxyacetophenones was used for the synthesis of amines. Amines were converted to sulfamoylcarbamates with chlorosulfonyl isocyanate (CSI) in the presence of BnOH.

Design, synthesis, and optical resolution of a novel non-natural chiral auxiliary, 1-(2,5-dimethoxyphenyl)ethylamine. Application to diastereoselective alkylation of aldimines
A chiral amine, 1-(2,5-dimethoxyphenyl)ethylamine, was found to be an effective chiralauxiliary for the diastereoselective alkylation of its aldimines with alkylmetals. The 1-(2,5-dimethoxyphenyl)ethyl group of the chiralauxiliary could be removed by the acetylation and then oxidation of the resultant alkylated product, accompanying an amino-transfer from the chiralauxiliary to the final product
