Steps:
1.2; 2.2; 3.2
(2) taking the above dried Fmoc-DOPA-OH (2.1 g, 5 mmol) intermediate,a magnetic stirrer, and DMP (6.13ml, 50mmol),Add to a 100ml two-necked flask,Add a rectifying head to the vertical bottle opening of the flask.The outlet of the distillation head is connected to an oil seal.The side bottle mouth is sealed with a rubber stopper for sampling. After argon gas is applied for 5 minutes, 50 ml of anhydrous toluene (3A molecular sieve drying) is added to make a methanol tape.Continue to argon for 20 minutes. Then, depressurize to about 300hPa,The oil bath was heated to an oil temperature of 80 ° C, and no additional catalyst was added.The progress of the reaction was monitored by thin layer chromatography (TLC).And compared with Fmoc-DOPA (Acetonide)-OH standard.When the temperature rises to 115 ° C, the liquid begins to distill,After 15 minutes, 10-13 ml of liquid was distilled off.After 1 hour of reaction, the yield by TLC was about 90%.
