PROCEDURE

实验过程

Condensation of BocProOH (4.63 g.) and MeDTrpOMe (5.00 g.) by the mixed anhydride method using diphenylphosphinyl chloride gave BocPro-MeDTrpOMe in 69% yield. Demethylation of BocPro-MeDTrpOMe (6.33 g.) using aqueous sodium hydroxide gave BocPro-MeDTrpOH in 77% yield. Condensation of BocPro-MeDTrpOH (3.60 g.) and HPheOBz (3.70 g.) using dicyclohexylcarbodiimide and N-hydroxysuccinimide gave BocPro-MeDTrp-PheOBz in 83% yield. Debenzylation of BocPro-MeDTrp-PheOBz (4.60 g.) by hydrogenation with palladium catalyst gave BocPro-MeDTrp-PheOH in 100% yield.
