摘要: Abstract The action of thiols on 1,2,3,4-tetra- O -acetyl-β- D -xylopyranose gave 2- and 5-alkylthiopentose dithioacetals alkyl 1-thio- -xylopyranosides. On treatment with trifluoroacetic acid- 3- -acetyl-1,2- -isopropylidene-α- -xylofuranose derivatives rapidly formed 4- -acetyl-2,3-dialkylthio- -ribose dithioacetal derivatives, which were in turn converted into -acetel-3- S -benzyl-2,5-epithio-3-thio- (or -arabinose) dithioacetal.
