YieldReaction ConditionsOperation in experiment
General procedure: 100mg 2-chlorotrityl resin (0.5mmol/g) was swollen in dry DCM for 30min and treated with the first building block (2.0equiv) and DIEA (4.0equiv) in dry DCM. After it was shook for 1h, 80muL MeOH was added to cap the unreacted resin for another 20min. The loaded resin was washed by DCM (3×2mL) and DMF (3×2mL). Fmoc deprotection was achieved by shaken with 2mL 20% solution of piperidine in DMF for 20min. The following Fmoc- or Boc-amino acids (4.0equiv) was coupled using 32 HATU (4.0equiv) as coupling reagent and DIEA (8.0 equiv) as base. The mixture was shaken in DMF for 1h. After each Fmoc deprotection and coupling reaction, the resin was washed by DMF (3×2mL), DCM (3×2mL) and DMF (3×2mL). The loaded resin was washed by DCM (3×2mL) and then a solution of Pd(PPh3)4 (1.0equiv) and phenylsilane (25equiv) in 2mL anhydrous DCM was added. The mixture was shaken for 1h under the protection of dry argon. After Alloc deprotection was completed, the resin was washed by DMF (3×2mL), DCM (3×2mL) and DMF (3×2mL). After coupling of the last building block, the resin was washed by DCM (3 2 mL), DMF (3 2 mL) and DCM (5 2 mL). Then a cocktail of DCM/AcOH/TFE (v/v/v = 8:1:1) was added to the resinand shaken for 1.5 h. Then the resin was filtrated off and rinsedwith DCM (5 2 mL). The combined filtrates were concentrated under low pressure and azeotroped several times with DCM to remove the Acetic acid. The side-chain-protected peptides were obtained as white solid.
