| titleOfInvention | Process for the preparation of ethyl-6-(formyl-oxy)- and ethyl-6-(trichloroacetimidoyl-oxy)-4-hexenoate |
| abstract | The present invention relates to a process for the preparation of ethyl 6- (formyloxy) -4-hexenoate and ethyl 6- (trichloroacetimidyloxy) -4-hexenoate. According to the invention, they are dehydrated and formylated during the thermal reaction in the presence of erythritol formic acid; the 4- (formyloxy) -3-hydroxy-1-butene obtained is reacted with triethyl orthoacetate under thermal reaction conditions and the resulting ethyl 6- (formyloxy) -4-hexenoate is prepared; and optionally converting into ethyl 6-hydroxy-4-hexenoate in the presence of ethanol and hydrochloric acid; by reacting it with trichloroacetonitrile to form ethyl 6- (trichloroacetimidyloxy) -4-hexenoate; and, if desired, converting the acid into a pharmaceutically acceptable salt.
