A new synthetic route of Cyclopent-3-enol

According to the analysis of related databases, 14320-38-8, the application of this compound in the production field has become more and more popular.

Electric Literature of 14320-38-8, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 14320-38-8, name is Cyclopent-3-enol. This compound has unique chemical properties. The synthetic route is as follows.

Cyclopent-3-enol (2.1 g, 24.97 mmol) was dissolved in CH2CI2 (30 ml,). TIPS-Cl (10.58 mL, 49.9 mmol) was added, followed by imidazole (3.40 g, 49.9 mmol). The mixture was stirred at room temperature for 2 days. White solid was filtered out and washed with small amount of DCM. The organic solution was evaporated and the residue was purified by silica gel chromatography (80 g silica gel column, 0-50% EtOAc/hexane gradient). Removing solvent gave (cyclopent-3-en-l -y]oxy)triisopropylsilane (4.92 g, 20.46 mmol, 82 % yield) as a colorless oil. NMR (400 MHz, CDCb): delta ppm 5.67 (2 H, s), 4.63 (1 H, t, ./ 3.63 Hz), 2.62 (2 H, dd, ./ 14.97. 6.82 Hz), 2.20 – 2.45 (2 H, m), 1.00 – 1.13 (21 H, m).

According to the analysis of related databases, 14320-38-8, the application of this compound in the production field has become more and more popular.
