Sulphonamidomercuration; a new method for amination of olefins
Abstract
The addition of toluene-p-sulphonamide to olefins in the presence of anhydrous mercury(II) nitrate and subsequent sodium borohydride reduction leads to the corresponding N-alkyl-sulphonamides; the use of 1, 4- and 1,5-dienes yields saturated nitrogen-containing heterocycles, the synthesis of tosylated pyrrolidine being a stereoselective reaction.
