Abstract
Process for the dichloroacetylation of aminoalcohols, characterized in that an arylsulfonate or sulfinate of 1-p-nitrophenyl-2-amino-1,3-propanediol is reacted with acid chlorides to obtain compounds of the general formula ** (See formula) ** wherein R is an acyl group or hydrogen, R1 is a substituent on the aromatic ring ∅ or hydrogen; and x = 2 or 3; by reacting the above compounds, in anhydrous solvents, with 1,3-dioxolane of the general formula ** (See formula) ** wherein R 'is a low molecular weight alkyl or a hydrogen atom, to obtain a final compound with the following structural formula ** (See formula) ** wherein R is an acyl group or hydrogen.
