摘要: Abstract The intramolecular cyclization of O -tosyl derivatives dithioacetals d -ribose, -arabinose, and -glucose was investigated. p -Toluenesulfonylation diethyl dithioacetal gave 3,6-anhydro- dithioacetal. Variously substituted 5- -tosyl- dibenzyl either 2,5-anhydro- l -idose dithioacetal, benzyl 1,5-dithio- -idopyranoside, or Likewise, 4- 1,4-dithio- -galactofuranoside derivatives.
