61995-20-8, Benzyl 3-oxopiperidine-1-carboxylate is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,61995-20-8
(3) To a solution of 83.7 g of 1-benzyloxycarbonyl-3-piperidone dissolved in 1.2 liters of methylene chloride was added 55.0 g of (R)-(+)-1-(1-naphthyl)ethylamine, and after the mixture was stirred at room temperature for 2 hours, 69 ml of acetic acid and 160 g of sodium triacetoxy borohydride were added to the mixture, and the mixture was stirred at room temperature for 15 hours. To the reaction mixture was added an aqueous sodium hydroxide to make the mixture basic, and then, chloroform was added to the mixture, the mixture was stirred and the liquids were separated. The organic layer was dried and concentrated, and the residue was purified by silica gel column chromatography (hexane: ethyl acetate=4:1?0:1) to obtain 98.7 g of benzyl 3-[(R)-1-(naphthalen-1-yl)ethylamino]-piperidine-1-carboxylate. MS·APCI (m/z): 389 [M+H]+
As the paragraph descriping shows that 61995-20-8 is playing an increasingly important role.
