873924-08-4, tert-Butyl 9-oxo-3-azaspiro[5.5]undecane-3-carboxylate is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,873924-08-4
9-Benzo[b]thiophen-2-yl-3-aza-spiro[5.5]undec-8-eneWas prepared according to method A with the following variation: n-BuLi (1.6 M in hexanes (4 ml_, 6.4 mmol)) was added drop-wise to a solution of benzothiophene (778 mg, 5.80 ml_) in diethyl ether (10 ml_). The reaction was warmed to reflux for 1 h and then cooled to -780C. 9-Oxo-3-aza-spiro[5.5]undecane-3-carboxylic acid terf-butyl ester (500 mg, 1.87 mmol) in diethyl ether was added drop-wise and the mixture was stirred at -780C for 2 h. Mp. 107.3-110.2C.
The synthetic route of 873924-08-4 has been constantly updated, and we look forward to future research findings.
