REFERENCES

• Can be used to introduce the 3-pentyl (Pen) group for protection of the phenolic OH group of tyrosine residues in peptide synthesis. See Appendix 6. The Pen group can be introduced in the presence of NaH in DMF. In comparison with other common OH protecting groups, Pen is relatively stable to 50% TFA in dichloromethane and completely stable to 20% piperidine in DMF, but can be cleaved with HF in the presence of a cation scavenger, e.g. anisole or p-cresol: Terahedron Lett., 39, 7117 (1998).
