PROCEDURE

实验过程

To a solution of 17-ethyl-1,14-dihydroxy-12-[2'-(4"-(tert-butyldimethylsiloxy)-3"-allyloxycyclohexyl)-1'-methylvinyl]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo[22.3.1.04,9 ]octacos-18-ene-2,3,10,16-tetraone (165 mg) in dry methylene chloride (4 ml) was added an excess of 2,6-lutidine (41 μl) and the mixture was stirred at room temperature. After 10 minutes, tert-butyldimethylsilyl trifluoromethanesulfonate (49 μl) was added via syringe. After 1 hour the reaction mixture was diluted with ethyl acetate, extracted from saturated sodium bicarbonate, washed with brine and the organic phase dried over magnesium sulfate. Removal of the solvent in vacuo and flash chromatography on silica gel (ethyl acetate:hexane (1:4)+1% methanol) gave the title compound (130 mg).
