Reference of 696-07-1, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 696-07-1, name is 5-Iodouracil. A new synthetic method of this compound is introduced below.
General procedure: To a solution of 5-iodopyrimidine (0.84 mmol) in anhydrous DMF (7 mL) were added the terminal alkyne (2.5 mmol), Pd(PPh3)4 (0.08 mmol), CuI (0.08 mmol) and Et3N [or (iPr)2EtN] (1.68 mmol). Method A: The reaction mixture was stirred at room temperature overnight. The extent of the reaction was monitored by TLC and the solvent was evaporated in vacuo and the residue purified by column chromatography (initial eluent CH2Cl2, then CH2Cl2/MeOH = 40:1) to afford 1-10a and 1-6b. Method B: The synthesis was carried out at 50 C for 30 min under microwave irradiation (300 W, 1 bar, Milestone start S microwave oven). Purification by column chromatography (initial eluent CH2Cl2, then CH2Cl2/MeOH = 40:1) afforded compounds 1-10a and 1-6b.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,696-07-1, its application will become more common.
