A novel synthesis of sulfamoyl nucleosides

Haukur Kristinsson; Kurt Nebel; Anthony C. O'Sullivan; Fritz Struber; Tammo Winkler; Yasuchika Yamaguchi

Abstract The sulfamoylated ribose derivative 8 was prepared on a kilogram scale, and used in conjunction with various heterocycles to prepare a series of natural and unnatural 5-O-sulfamoyl nucleosides ( 10 – 32 ). A modification of the Vorbruggen-Hilbert-Johnson reaction conditions for nucleoside formation was used.
