768-66-1,768-66-1, 2,2,6,6-Tetramethylpiperidine is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Compound 35 (31.7 g, 127 mmol) and THF (200 mL) were loaded into a three-necked flask, and then the mixture was cooled to -78C. A lithium 2,2,6,6-tetramethylpiperidine solution prepared in advance from a 1.55-M solution of n-BuLi in hexane (82 mL, 127 mmol), 2,2,6,6-tetramethylpiperidine (17.9 g, 127 mmol), and THF (50 mL) was added to the mixture, and then the whole was stirred at -78C under an Ar atmosphere for 2 hours. After that, triisopropyl borate (71.6 g, 381 mmol) was added to the resultant, and then the mixture was stirred at -78C for 2 hours. After that, the temperature of the mixture was slowly returned to roomtemperature, and then the mixture was left to stand overnight. After the completion of the reaction, methanol (50 mL) was added to deactivate the resultant, and then the mixture was concentrated so that its volume might be reduced by about half. CH2Cl2 (200 mL) and 2N HCl (120 mL) were added to the resultant, and then the mixture was stirred at room temperature for 2 hours. The resultant sample was transferred to a separating funnel and extracted with CH2Cl2. The solution was dried with MgSO4, and was then purified by silica gel column chromatography. The purified product was concentrated to dryness, and then the solid was subjected to dispersion washing with toluene. Thus, a white solid was obtained in an amount of 27.5 g in 74% yield.
As the paragraph descriping shows that 768-66-1 is playing an increasingly important role.
