実験手順

To a stirred mixture of 17-ethyl-1,14-dihydroxy-12-[2'-(3",4"-dihydroxycyclohexyl)-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 (250 mg, 0.32 mmol, 1 eq) and Cu(OAc)2 (10 mg, 0.055 mmol, 0.17 eq) in CH2Cl2 (5.5 ml) in a round bottom flask equipped with a magnetic stir-bar was added tri(2-naphthyl) bismuth diacetate [prepared immediately prior to use by addition of acetic acid (0.100 ml, 1.75 mmol, 5.46 eq) to a suspension of tri(2-naphthyl)bismuth carbonate (350 mg, 0.538 mmol, 1.7 eq) in CH2Cl2 (5.5 ml)]. The reaction flask was fitted with a reflux condenser and the mixture warmed to 40° C. for 4 hours then stirred at room temperature. After 3 days the reaction mixture was diluted with saturated aqueous NaHCO3 and extracted 3 times with CH2Cl2. The extracts were combined, dried over anhydrous Na2SO4, filtered, and concentrated in vacuo. The products were separated and purified by preparative TLC on silica gel (eluted with 3:1 hexanes/acetone) to give 63 mg of 17-ethyl-1,14-dihydroxy-12-[2'-(3"-(napth-2-yloxy)-4"-hydroxycyclohexyl)-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 and 49 mg of 17-ethyl-1,14-dihyroxy-12-[2'-(4"-(naphth-2-yloxy)- 3"-hydroxycyclohexyl)-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. (1H NMR was consistent with the desired structure).
