FREMGANGSMAADE TIL FREMSTILLING AF TRIPEPTIDER |
摘要 |
<p>Process for preparing tripeptides of the general formula I U-A-B-C-OH I in which U is hydrogen or a urethane protective group and A, B and C are amino acids, by reacting a compound of the general formula II U'-B-OH II in which U' is a urethane protective group which can be eliminated by hydrogenolysis, with a compound of the general formula III H-C-OR III in which R is alkyl, by the PPA method, eliminating U', reacting the compound obtained in this way with a compound of the general formula IV H-B-C-OR IV by the PPA method and subsequently eliminating R enzymatically.</p> |
