N-protected amino acids and peptides |
| abstract |
NOFEL N-PROTECTED AMINO ACIDS REPRESENTED BY THE FORMULA R-C*C-C(-R1)(-R2)-OOC-NH-A WHERE R IS H, CL, PHENYL OR SUBSTITUTED PHENYL; R1 IS H OR C1-C4 ALKYL, R2 IS C1-C4 ALKYL AND A IS THE RESIDUE OF AN AMINO ACID, ARE OBTAINED BY REACTING AN ACETYLENIC CHLORO OR FLUOROFORMATE ESTER OR A PHENHLYL CARBONATE ESTER WITH AMINO ACIDS. N-PROTECTED AMINO ACIDS ARE EMPLOYED IN METHOD OF PEPTIDE SYNTHESIS COMPRISING COUPLING AN N-PROTECTED AMINO ACID OR AN ACTIVE ESTER THEREOF WITH AMINO ACIDS OR PEPTIDES TO PROVIDE N-TERMINAL PROTECTED PEPTIDES. HYDROENOLYSIS OF N-PROTECTED PEPTIDE PRODUCTS OVER 5 PERCENT PD/C AT NEUTRAL OR ACIDIC PH AFFORDS DESIRED PEPTIDES. ACRTYLENIC N-PROTECTING GROUPS PROVIDED ARE READILY CLEAVED IN THE PRESENCE OF AMINO ACIDS OR PEPTIDES HAVING SULFUR CONTAINING GROUP. |
