| 抄録 | The first total synthesis and structural identification of cyanopterin, a pterin glycoside isolated from the cyanobacterium Synechocystis sp. PCC 6803, has been accomplished. The synthesis was achieved by convergent coupling of three key derivatives: d-glucuronate, d-galactose, and 6-hydroxymethylpterin. An α-selective glycosylation enabled efficient construction of the glucuronate–galactose disaccharide, while subsequent β-exclusive glycosylation with the 6-hydroxymethylpterin derivative furnished the desired pterin–disaccharide glycoside. Final deprotection provided cyanopterin in its natural form, allowing confirmation of its precise structure.
