Isoacyl dipeptides

Isoacyl dipeptides are useful synthetic building blocks for preparing
1. Difficult peptides
2. Cyclic peptides
3. Peptides by fragment condensation
Use isoacyl dipeptides to:
1. Improve synthetic purity and yield of difficult peptides
2. Improve peptide solubility for easier HPLC purification
3. Help induce cyclization of linear peptides
4. Prevent racemization in coupling of peptide segments
