With ammonium chloride; magnesium; In tetrahydrofuran; | EXAMPLE 5 (R)-1-(3-(9H-Tribenzo[a,c,e]cyclohepten-9-ylidene)-1-propyl)-3-piperidine-carboxylic acid hydrochloride STR7 A solution of cyclopropylmagnesium bromide in dry tetrahydrofuran (prepared from cyclopropylbromide (4.54 g, 37.5 mmol), magnesium turnings (0.91 g, 37.5 mmol) and dry tetrahydrofuran (30 ml)) was placed under an atmosphere of nitrogen. A solution of 9H-tribenzo[a,c,e]cyclohepten-9-one (1.92 g, 7.5 mmol) (prepared according to W. Tochtermann, Chem. Ber., 97, 1329 (1964)) in tetrahydrofuran (20 ml) was added dropwise and when addition was complete the mixture was heated at reflux temperature for 30 minutes. The reaction mixture was cooled on an ice-bath and saturated ammonium chloride (50 ml) was added carefully. The organic layer was separated and the aqueous phase extracted with diethyl ether (2*100 ml). The combined organic extracts were dried (MgSO4) and the solvent was evaporated in vacuo affording 2.69 g of 9-cyclopropyl-9H-tribenzo[a,c,e]cyclohepten-9-ol. | |

With silica gel; In dichloromethane; | To a stirred solution of diketone 6 (0.50 g, 1.81 mmol) in CH2Cl2 (30mL) at r.t. under argon were added TIPSOTf (0.6 mL, 2.15 mmol) andEt3N (0.25 mL, 2.00 mmol). The mixture was stirred at r.t. for 1.5 h, then filtered through a short pad of silica gel. The filtrate was concentrated under reduced pressure. The crude product was dissolved inCH2Cl2 (20 mL), and treated with DDQ (0.41 g, 1.81 mmol). The mixture was stirred at r.t. for 1.5 h, and then the reaction was quenched with H2O. The mixture was extracted with CH2Cl2, and the extractswere dried (Na2SO4), filtered, and concentrated under reduced pressure(single spot in TLC). The crude product (0.42 g) was purified bytrituration with hexane to give a white solid; yield: 0.26 g (1.03mmol, 57%); mp 177-178 C; Rf = 0.53 (EtOAc-hexane, 1:4). |
