반응 단계
3.30 g of 3,4,5-triacetoxy-6-(2-formyl-thiophen-3-yloxy)-tetrahydropyran-2-ylmethyl actate were dissolved in 60 ml of dioxane. 6.43 g of methyltriphenylphosphonium bromide, 5.37 g of potassium carbonate and 0.25 ml of water were added, and the solution was refluxed for 4 h. The solution was concentrated and purified by column filtration. 2.89 g of the product with the molecular weight: 456.47 (C20H24O10S), MS (ESI): 479.10 (M+Na+); 474.10 (M+NH4+) were obtained.
