Crystal structure of N-(tert-butoxycarbonyl)phenylalanyldehydroalanine isopropyl ester (Boc–Phe–ΔAla–OiPr)

Crystal structure of N-(tert-butoxycarbonyl)phenylalanyldehydroalanine isopropyl ester (Boc–Phe–ΔAla–OiPr)

In the title compound, the dehydrodipeptide (Boc–Phe–ΔAla–OiPr, C20H28N2O5), the molecule has a trans conformation of the N-methylamide group. The geometry of the dehydroalanine moiety is to some extent different from those usually found in simple peptides, indicating conjugation between the H2C=C g...
