Participants

Reaction Steps

A solution of 4-nitrophenyl chloroformate (62 mg, 300 μmol) in dichloromethane (2.5 mL) was added dropwise into a solution of (8E,12E,14E)-3,6,21-tri(1-ethoxyethoxy)-7-hydroxy-6,10,12,16,20-pentamethyl-18,19-epoxytricosa-8,12,14-trien-11-olide (35 mg, 49.2 μmol), triethylamine (61 mg, 600 μmol) and dimethylaminopyridine (4 mg, 30 μmol) in dichloromethane (2.5 mL), followed by stirring at room temperature for 2.5 hours under nitrogen atmosphere. Ethyl acetate, water and saturated sodium bicarbonate aqueous solution were added to the reaction mixture, and the mixture was extracted with ethyl acetate, then the organic layer was washed with water. The resulting organic layer was dried over anhydrous magnesium sulfate, filtered and then evaporated to give the title crude compound (92.2 mg) as a yellow oil. This was used for the following reaction without purification.
