实验过程
Dehydroryanodine (100 mg, 0.2 mmol), N-(p-iodobenzoyl)-β-alanine (50 mg, 0.22 mmol) and DMAP (2 mg, 0.02 mmol), all dried over P2O5, were dissolved in a solvent mixture of CH2Cl2 (10 ml) and tetrahydrofuran (0.1 ml) dried over Molecular Sieve. To the stirred solution, dicyclohexylcarbodiimide (DCC, 52 mg., 0.25 mmol) was added at once and the stirred reaction maintained at room temperature for 6 hours. Water (0.1 ml) was added to inactivate excess DCC and stirring was continued for 30 minutes. The crystals of dicyclohexylurea thus formed were filtered off and washed twice with CH2Cl2.
