Janus glycosides of next generation: Synthesis of 4-(3-chloropropoxy)phenyl and 4-(3-azidopropoxy)phenyl glycosides

Add time:07/11/2019    Source:sciencedirect.com

Efficient procedures for the preparative synthesis of per-O-acyl derivatives of 4-(3-chloropropoxy)phenyl (CPP) glycosides of a series of common mono- and disaccharides (d-glucose, d-galactose, d-mannose, l-rhamnose, d-arabinofuranose, d-glucosamine, lactose) are described. The CPP glycosides obtained were transformed in almost quantitative yields to the corresponding unprotected 4-(3-azidopropoxy)phenyl (APP) glycosides, which could become next-generation Janus glycosides with cleavable spacer aglycon, ready for conjugation or further transformation.
