As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 14320-38-8, name is Cyclopent-3-enol, molecular formula is C5H8O, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Recommanded Product: Cyclopent-3-enol
To a dry, argon purged three-neck round bottom flask (1000 mL) were added anhydrous dichloromethane (100 mL) and Et2Zn (28 mL, 273 mmol) at 0 C. (CAUTION: Source of argon can not be from needle. Use appropriate glass adapter only. A second bubbler can also be attached to the flask to prevent excessive pressure build up.) Cyclopenten-3-ol (10.0 mL, 119 mmol) was then added dropwise (large quantity of ethane gas was produced) to the flask and the reaction mixture was allowed to stir until the evolution of gas had ceased. Diiodomethane (22 mL, 242 mmol) was then added dropwise over a period of 30 minutes. The reaction was allowed to warm to room temperature and continued to stir overnight under a positive flow of argon, at which point TLC analysis had indicated complete disappearance of the starting alcohol. The reaction was then diluted with CH2Cl2 and quenched with 2M HCl (white precipitate should be completely dissolved). The biphasic mixture was poured into a reparatory funnel and the organic layer was collected. The solvent was removed under reduced pressure until 100 mL of material containing compound 301 remained.
With the rapid development of chemical substances, we look forward to future research findings about 14320-38-8.
