摘要:Provided is a process for recycling waste residue from the synthesis of hexachlorocyclotriphosphazene. The process comprises: reacting waste residue separated out after a synthesis reaction of hexachlorocyclotriphosphazene is finished with an ammonia source, the ammonia source being liquid ammonia, ammonia gas, ammonia water, ammonium bicarbonate, ammonium carbonate or a combination thereof; adjusting the pH value at an end point to 6-10; subjecting the obtained reaction product to solid-liquid separation so as to obtain a filtrate and a filter cake; subjecting the filter cake to post-treatment so as to obtain a recovered metal chloride catalyst; extracting the filtrate by using chlorobenzene, i.e. an extracting agent, so as to obtain an extract phase and a raffinate phase; rectifying the extract phase to obtain chlorobenzene and recovered pyridine or pyridine derivatives; and dehydrating the raffinate phase to obtain recovered ammonium chloride. By means of the process, high-degree recycling and regeneration of waste residue from the synthesis of hexachlorocyclotriphosphazene are achieved, the recovery rate of pyridine or pyridine derivatives from the waste residue can reach 95-99% or higher, the recovery rate of ammonium chloride and the metal chloride catalyst can reach 98% or higher, and no new waste residue is generated throughout the whole process.

摘要:The invention relates to a new enantioselective synthesis for the preparation of optically active 14-oxo-E-homo-eburnane derivatives of the formula (Ia) ##STR1## wherein R 1 is alkyl having from 1 to 4 carbon atom. In the synthesis optically active 6-alkoxycarbonylhexahydroindoloquinolizinium salts are employed as starting materials, which contain a center of chirality at the site of attachment of the carboxyl group. This center of chirality preserves the optical activity of the optically active tryptophan ester from which this compound has been prepared until a new center of chirality is formed in the molecule in a configuration corresponding to the desired end product. The carboxyl group, which is not needed in the end product and only serves to preserving the optical activity can then be eliminated. n Compounds of the formula (Ia) are known in the art and may be used in the synthesis of (+)-vincamine and (+)-apovincaminic acid ethylester.
