In methanol; at 65℃; for 18h; | [0041] 8.7 g (50 mmol) of <strong>[3081-61-6]theanine</strong> and 19.3 g (53.6 mmol) of maltose were added in 130 ml of methanol and refluxedat 65 C for 18 hours. After the completion of the reaction, the mixture was kept at the room temperature for 3 hoursand subjected to filtration to obtain a mixture of maltulosyl <strong>[3081-61-6]theanine</strong> represented by the following formula 3 or 4 (12.9 g,52% yield) as a white powder.[0042] 1H NMR(D2O, delta): 5.24(1H), 4.20(1H), 4.07(1H), 3.99(2H), 3.79(7H), 3.57(1H), 3.43(1H), 3.33(1H), 3.20(2H)2.46(2H), 2.17(2H), 1.11(3H) (Peaks are shown for major compounds only.)[0043] LC-Mass: 499 [M+H][ |
