| abstract | PURPOSE: To obtain the title compound such as vinblastine having antitumor activity and useful as an anticancer agent by adding an inorganic anion source, trivalent iron source and hydride source to a specific compound used as a starting raw material in the presence of oxygen. n CONSTITUTION: An inorganic anion source (preferably Cl - , Br - , I - , SO, etc., except such an inorganic anion as to produce an insoluble iron salt such as CO or PO), trivalent iron source (preferably hydrochloric acid salt, sulfuric acid salt or nitric acid salt) and hydride source (e.g. sodium borohydride) are added to a compound (e.g. anhydrovinblastine) expressed by formula I (R 1 is H, lower alkyl or formyl; R 2 is lower alkoxycarbonyl or amide; R 3 is acetoxy or OH) and used as a starting raw material in the presence of oxygen to provide the aimed compound expressed by formula II (R 4 is OH and R 5 is Et or R 4 is Et and R 5 is OH). n COPYRIGHT: (C)1990,JPO&Japio |
