참여 물질

반응 단계

In a 10 mL rb flask was added (3aR,5R,6S,7R,7aR)-5-(azidomethyl)-2-(ethylamino)-5,6,7,7a-tetrahydro-3aH-pyrano[3,2-d][1,3]thiazole-6,7-diol (40 mg, 0.15 mmol, 1.00 eq.), copper turnings (66 mg; 1.05 mmol; 7.00 eq.) and copper(II)sulfate pentahydrate (7.5 mg; 0.03 mmol; 0.20 eq.). The flask was evacuated and filled with nitrogen. This procedure was repeated twice before ethanol (0.5 ml)/water (0.7 ml)/2-methylpropan-2-ol (1.3 ml) and 2-phenylbut-3-yn-2-ol (22 mg; 0.45 mmol; 3.00 eq.) was added into the mixture and stirred for 24 h to get the reaction completed. Product formation was confirmed by LCMS. The solution was diluted with 2 mL H2O, dried and separated with mass based prep HPLC to afford the desired product.
