Abstract
Process for selectively preparing the mono- and di-acyl derivatives of the 1-p.nitrophenyl-2-amino-1,3-propanediols, in particular the N-momo-and the n, O-diacilderivatives, characterized by the fact that the 1-p.nitrophenyl-2-amino-1,3-propanediols are treated with the chloride of an acid dissolved in the corresponding acid, saturated with hydrochloric acid, and that the o, O-diaclic hydrochlorides, thus obtained, are optionally subjected to the simple migration in n, of an acyl group, to obtain the n, O-diacilderivatives, or to the aforementioned migration with simultaneous saponification of the other acyl group to obtain the N-monoacyl-derivatives.
