YieldReaction ConditionsOperation in experiment
62% With trifluoroacetic acid; In dichloromethane; at 0 - 20℃; for 3h; General procedure: A mixture of 4?-demethylepipodophyllotoxin (DMEP) (400mg 1mmol) and SH-containing building blocks in dichloromethane (15mL) at 0C was mixed with 1mL of TFA as the catalyst. After stirring the reaction mixture for 2-3hat room temperature and maximal conversion was reached (3h, monitored by TLC), the resultant mixture was washed with saturated NaHCO3 (20mL×2) and extracted with CH2Cl2 (45mL×2). The organic layer was dried over MgSO4, and the solvent was evaporated to give a crude residue, which was purified by flash column chromatography (petroleum ether: dichloromethane: ethyl acetate, 3:2:1) to afford the target compounds. The purity of compounds was determined by HPLC with a thermo-C18 (250mm×4.6mm, 5mum) column as the stationary phase and methanol-water (35:65) as the mobile phase at ambient temperature and a flow rate of 2.0mL/min.
