885279-92-5, 1-Boc-1,8-diaza-spiro[4.5]decane is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A flask was charged with N-(1H-pyrazol-4-yl)acetamide (1.00 g, 7.99 mmol, 1.00 equiv), DCM (15 mL) and DIPEA (2.06 g, 15.9 mmol, 2.00 equiv). 4-Nitrophenyl chloroformate (1.78 g, 8.83 mmol, 1.11 equiv) in DCM (5 mL) was added dropwise at 0 C. The mixture was stirred for 2 h at room temperature, then t-butyl 1,8-diazaspiro[4.5]decane-1-carboxylate (1.92 g, 7.99 mmol, 1.00 equiv) was added. The resulting solution was stirred overnight at room temperature and quenched by water (20 mL). The mixture was extracted with DCM (3 x 20 mL) and the organic layers were combined, washed with water (3 x 20 mL), dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The residue was chromatographed to provide 2.23 g (71% yield) of t-butyl 8-(3 -acetamido- 1H-pyrazole- 1 -carbonyl)- 1, 8-diazaspiro[4. 5]decane-1-carboxylate as an off-white solid. LCMS (ESI, m/z): 392 [M+H]., 885279-92-5
885279-92-5 1-Boc-1,8-diaza-spiro[4.5]decane 34178602, apiperidines compound, is more and more widely used in various fields.
