摘要：

The syntheses of 5''-O-sulfamoyl and 5''-O-carbamoyl tiazofurin (9 and 12) are described. One pot reaction of 2'',3''-O-isopropylidene-tiazofurin (7) with hexabutyldistannoxane and sulfamoyl chloride gave the corresponding 5''-O-sulfamoyl ester, which was deprotected to yield 9. Compound 7 reacted with phenyl chloroformate to give the 5''-O-carbophenoxy derivative which on treatment with ammonium hydroxide followed by deisopropylidenation afforded 12. Improvements on the synthetic route to the starting tiazofurin are also reported.
