Sucres acétyléniques hétérosubstitués sur la triple liaison

Abstract gem -Dihalogeneno sugars, such as the 6,6-dibromo, 6,6-dichloro, and 6,6-difluoro derivatives of 5,6-dideoxy-1,2- O 0-isopropylidenehex-5-enofuranoses, easily obtained by a Wittig reaction on aldehydo -sugars, gave various derivatives of 5,6-dideoxy-5-ynofuranoses having a bromo, chloro, phenylthio, diethyl phosphonate, phenylphosphine, and phenylphosphine oxide substituent at C-6. The methods of preparation, generally giving good yields, as well as the spectroscopic data of the compounds obtained are described.
