| Abstract | The first total synthesis and unambiguous structural elucidation of microcystbiopterin C, a pterin glycoside isolated from a Microcystis bloom, has been achieved. Two candidate biopterin glycosides (5a and 5b) corresponding to the proposed structures of microcystbiopterin C were synthesized by glycosylation of a suitably protected biopterin derivative 10 with 2,4-di-O-benzoyl-6-deoxy-3-O-methyl-α-L-mannopyranosyl bromide (9) and the corresponding α-D-mannopyranosyl bromide (22), respectively, followed by stepwise deprotection. Detailed comparison of the NMR data and the specific rotation of compounds 5a and 5b with those of the natural product established that microcystbiopterin C possesses the structure of 2′-O-(6-deoxy-3-O-methyl-α-D-mannopyranosyl)biopterin (5b).
