| abstract | NEW MATERIAL:A compound expressed by formula I (n is 0-9; Ac is formula II; R and R' are H, alkyl or phenyl). n USE: A precursor of substrates for measuring enzymic activity. n PREPARATION: A compound expressed by formula III, together with α,α- dimethoxytoluene, p-toluenesulfonic acid and dimethylformamide, is stirred at 50-60°C under reduced pressure for 4hr and then cooled to ambient temperature. Pyridine, acetic anhydride and dimethylaminiopyridine are added and the resultant mixture is allowed to stand for 20hr, extracted with ethyl acetate and purified by silica gel chromatography. Furthermore, the reaction mixture is dissolved in methanol and 10% palladium carbon is added to carry out reaction under normal pressure in a hydrogen atmosphere for 6hr. After filtration, recrystallization from ethanol is performed to afford the objective derivative. n COPYRIGHT: (C)1990,JPO&Japio |
