A New Scaffold for the Stereoselective Synthesis of α-O-Linked Glycopeptide Mimetics
摘要:
alpha-O-Linked glycohomoglutamates are obtained as diastereomerically pure compounds by chemo-, regio-, and stereoselective cycloadditions between glycals and aspartic acid derivatives. The latter constitute orthogonally functionalized scaffolds for glycopeptide mimetics.
Disclosed is a dihydropyrimido fused ring derivative as a HBV inhibitor, and in particular relates to a compound shown as formula (I) or a pharmaceutically acceptable salt thereof.

The synthesis of an amino acid amide is reported, which contains two benzamidine cores, one placed in the amide part the other one within the sulfonyl N-capping group. The amino acid side chain bears the 6,7-dimethoxycoumarin fluorophore. The fluorescent amino acid was prepared by using the von-Pechmann reaction. The two corresponding nitrile groups of a precursor molecule were simultaneously converted
