Various substituted taurines have been synthesized expeditiously and practically in
satisfactory to good yields directly from amino alcohols using a two-step, one-pot
procedure, in which the amino alcohols undergo sulfuric acid esterification and subsequent
sodium sulfite substitution. Treatment of amino-substituted secondary alcohols using
the same procedure gave 2-substituted or 1,2-disubstituted taurines, indicating the
formation of aziridines as intermediates during the substitution step. This method
is one of the most efficient routes for preparing structurally diverse 2-substituted
and 1,2- and 2,2-disubstituted taurines.
