Abstract
Process for obtaining new arylsulfonates-2-amino-1-phenyl-1,3-propanediol, specifically p-toluenesulfonate-2-amino-1, p-nitrophenyl-1,3-propanediol, from phenacyl halides, characterized by to treatment alpha-haloacetophenones, whether or not substituted on the ring, with haxamethylenetetramine arylsulfonates; hydrolyzing the compound resulting from the above reaction to obtain arylsulfonates of alpha-aminoacetophenones; transforming these into sulfonamide derivatives by arylsulfonyl chlorides or arylsulfonic anhydrides; convert sulfonamides to beta-hydroxy-propiophenone derivatives by treating them with formaldehyde in the presence of basic catalysts and finally reducing the carbonyl of the resulting product, before or after acid hydrolysis, in the presence of aluminum alkoxides and alcohols of one to four atoms of carbon.
