1-(3-甲氧基呋喃-2-基)乙醇

反应条件: temp:90.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 2-(1-hydroxyethyl)-3-methoxy-furan (0.350 g, 2.5 mmole) in 4 ml of methanol and 1 ml of water was added to a solution of 2 ml of methanol and 5 ml of water as chlorine gas (2.5 mmoles) was added to the well stirred reaction. The temperature of the reaction was kept below -10° C. at all times. Following the addition the reaction was heated to 90° C. for 3 hours. After cooling, the reaction was adjusted to a pH 2.2 with 50% NaOH solution, the reaction was extracted with chloroform and the chloroform concentrated to yield maltol. was added to the well reaction was kept below -10° C. at all times the addition the reaction After cooling the reaction was extracted with chloroform the chloroform concentrated
