First total synthesis of a naturally occurring iodinated 5′-deoxyxylofuranosyl marine nucleoside

Sun, Jianyun,Dou, Yanhui,Ding, Haixin,Yang, Ruchun,Sun, Qi,Xiao, Qiang

, p. 881 - 889 (2012)

4-Amino-7-(5′-deoxy-β-D-xylofuranosyl)-5-iodo-pyrrolo[2,3-d] pyrimidine 1, an unusual naturally occurring marine nucleoside isolated from an ascidan, Diplosoma sp., was synthesized from D-xylose in seven steps with 28% overall yield on 10 g scale. The key step was Vorbrueggen glycosylation of 5-iodo-pyrrolo[2,3-d]pyrimidine with 5-deoxy-1, 2-O-diacetyl-3-O-benzoyl-D- xylofuranose. Its absolute configuration was confirmed.
