Reaction Steps

A solution of 1 (132 mg, 167 μmol) in CHCl3 (13 mL) was treated with a solution of Zn(OAc)2.2H2O (183 mg, 0.832 mmol) in MeOH (2.6 mL) at room temperature. The reaction was followed by TLC. The reaction was complete in 2 h. The reaction mixture was washed with saturated aqueous NH4Cl and extracted with CH2Cl2. The combined organic layer was dried (Na2SO4), concentrated and chromatographed [silica, hexanes/ethyl acetate (9:1)] to afford a pink solid (132 mg, 93%): 1H NMR δ 2.66-2.78 (m, 15H), 5.12-5.28 (m, 6H), 5.80-5.96 (m, 3H), 7.50-7.60 (m, 6H), 7.67 (d, J=8.4 Hz, 2H), 8.04-8.14 (m, 6H), 8.16 (d, J=8.4 Hz, 2H), 8.88-8.94 (m, 2H), 8.94-9.02 (m, 6H); MALDI-MS obsd 852.4; FABMS obsd 852.3193, calcd 852.3170 (C57H48N4Zn); λabs 424, 551 nm.
