Procedure

To a stirred solution of 17-ethyl-1,14-dihydroxy-12-[2'-(4"-hydroxy-3"-methoxycyclohexyl)-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 (100 mg, 0.126 mmol, 1 eq) and Cu(OAc)2 (2.8 mg, 0.014 mmol. 0.11 eq) in CH2Cl2 (1 ml) in a 16 mL screw-cap vial equipped with a magnetic stir-bar was added triphenyl bismuth diacetate [prepared immediately prior to use by addition of acetic acid (0.030 mL, 0.504 mmol, 4 eq) to a suspension of triphenyl bismuth carbonate (127 mg, 0.253 mmol. 2 eq) in CH2Cl2 (1 ml)]. The reaction vessel was capped and the mixture stirred for five days. The reaction mixture was diluted with several milliliters of saturated aqueous NaHCO3 and extracted 4 times with CH2Cl2. The organic extracts were combined, dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The product was isolated by preparative TLC on silica gel (eluted with 3:4 EtOAc/hexanes to afford 46 mg of 17-ethyl-1,14-dihydroxy 12-[2'-(4"-phenyloxy-3"-methoxycyclohexyl)-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, 13C NMR and mass spectral analysis were consistent with the desired structure.)
