标题 :Process for the synthesis of substituted carbodiimides
发明人：HUSSENET PATRICIA; LE GOFF PHILIPPE; SENNYEY GERARD
权利人:POUDRES & EXPLOSIFS STE NALE
摘要:The invention relates to a new process for the synthesis of a disubstituted carbodiimide, including a first stage of phosgenation of an N,N'-disubstituted urea in an organic solvent medium. n After this first stage ammonia is added to the reaction mixture without preliminary isolation of any intermediate compound. n The process is simple, relatively inexpensive and the yield is high. n Disubstituted carbodiimides are organic synthesis intermediates used especially in pharmaceutical chemistry as coupling agents in peptide synthesis.

权利人:SYNBIAS PHARMA AG
摘要:The present invention relates to a method for the synthesis of 7-ethyl-10-[4-(1-piperidino)-1-piperidino]carbonyloxycamptothecin (i.e. iriniotecan), comprising: (a) preparing 10-[4-(1-piperidino)-1-piperidino]carbonyloxycamptotecin; and (b) selectively ethylating the compound of step (a) at the 7-position, thus resulting in the preparation of 7-ethyl-10-[4-(1-piperidino)-1-piperidino]carbonyloxycamptothecin. The present invention is further directed to the use of 10-[4-(1-piperidino)-1-piperidino]carbonyloxycamptothecin (i.e. 7-des-ethyl-irinotecan) as intermediate in a method for the synthesis of irinotecan as described.
