Dipeptides (I) derived from an alpha -amino acid and a cyclopentane- beta -amino acid are new. Dipeptides of formula (I) and their salts derived from an alpha -amino acid and a cyclopentane- beta -amino acid are new.

Zusammenfassung: | Dipeptides (I) derived from an alpha -amino acid and a cyclopentane- beta -amino acid are new. Dipeptides of formula (I) and their salts derived from an alpha -amino acid and a cyclopentane- beta -amino acid are new. R , R = H; or R + R = form CH2; R = CH3 or -CH(CH3)CH2CH3; R , R = H; or R + R = form -(CH2)3-. An Independent claim is also included for the preparation of compounds (I). |
