One-step synthesis of C-2 dialkylamino-substituted 2′,3′-O-anhydro-lyxo-uridines: First report on the opening of 2,2′-O-anhydro-bridge of 2,2′-O-anhydrouridine by secondary amines.
摘要:
Secondary amines successfully opened the 2,2'-O-anhydro-bridge of 2,2'-O-anhydrouridines 8a and 8b in presence of 3'-O-mesyl group to produce compounds 10a-13a and 10b-13b, a new class of isocytidine derivatives.
