Abstract

Procedimiento par ala producción de compuestos orgánicos fundado en la epimerización de eritro-2-acilamido-1-nitrofenil-propano 1:3-dioles y caracterizado por esterificar un isómero óptico o racemato de la eritro-forma de uno de estos dioles o glicoles para formar el éster di-nítrico 1:3. del mismo; por tratar el di-éster con álcali para una oxazolina; por tratar la oxazolina producto de reacción con ácido para dar lugar con ello a la fisión o ruptura del anillo oxazolínico con objeto de formar un propanol producto de reacción; por tratar este propanol producto de reacción con álcali por cuyo medio se hidroliza el grupo 3-éster con ciclización simultánea para una oxazolina y por tratar la oxazolina resultante con un ácido y neutralizar luego la mezcla de reacción por tratamiento con una base.Procedure for the production of organic compounds based on the epimerization of erythro-2-acylamido-1-nitrophenyl-propane 1: 3-diols and characterized by esterifying an optical isomer or racemate of the erythro-form of one of these diols or glycols to form the di-nitric ester 1: 3. of the same; by treating the diester with alkali to an oxazoline; by treating the reaction product oxazoline with acid to thereby cause fission or cleavage of the oxazolinic ring to form a reaction product propanol; by treating this reaction product propanol with alkali by which the 3-ester group is hydrolyzed with simultaneous cyclization to an oxazoline and by treating the resulting oxazoline with an acid and then neutralizing the reaction mixture by treatment with a base.
