With N,N,N,N,-tetramethylethylenediamine; In (2S)-N-methyl-1-phenylpropan-2-amine hydrate; hexane; N,N-dimethyl-formamide; | (a) 2,3-Dimethoxy-naphthalene-1-carbaldehyde n-Butyl lithium in hexane (1.6 N, 31.3 ml) was gradually added to a solution of <strong>[10103-06-7]2,3-dimethoxynaphthalene</strong> (9.4 g) and N,N,N',N'-tetramethylethylenediamine (7.4 ml) in ether (150 ml) under argon at 0 C. The reaction mixture was stirred at room temperature for two hours, cooled to 0 C. and DMF (7.3 g) in ether (20 ml) added. The reaction mixture was stirred at room temperature overnight and poured in ice water. The product was extracted with ether, washed with water, dried, evaporated and recrystallized from ether. Yield: 4.2 g. 1H-NMR (DMSO-d6, 400 MHz): 10.68 (s,1H, CHO), 8.95-8.97 (m, 1H), 7.87-7.89 (m,1H), 7.80 (s,1H), 7.49-7.51 (m,2H), 4.00 (s,6H). |

61%; 38% | General procedure: In a round-bottomed flask equipped with a stirring bar and rubber septum was placed a 1 M solution of SnCl4 in anhydrous CH2Cl2 (1 mL, 1 mmol). To this solution was added PhSCF2H (1; 240.2 mg, 1.5 mmol) in anhydrous CH2Cl2 (1.5 mL), followed by a solution of an aromatic compound (0.5 mmol) in anhydrous CH2Cl2 (1 mL). The reaction was allowed to proceed for 2 h before it was quenched with a solution of IBX (140 mg, 0.5 mmol) in DMSO/H2O (4 mL; 3:1 v:v). After 2 h of stirring at rt, the reaction mixture was quenched by addition of a saturated aqueous solution of sodium thiosulfate (10 mL), then basified with a saturated aqueous solution of sodium hydrogen carbonate (10 mL), followed by stirring and extraction with CH2Cl2 (3 × 10 mL). The combined organic layers were washed with water (3 × 10 mL) and brine (10 mL), dried (anhydrous MgSO4), filtered and concentrated (aspirator). The residue was purified by PTLC, radial chromatography or column chromatography to furnish analytically pure product. |
