2-Haloethyl 1-Thioglycosides as New Tools in Glycoside Syntheses. Part 1. PrepaCharacteristics, General Reactions. — The synthesis and application of
12- 207 ration,
2-haloethyl 1-thioglycosides as leaving group in glycoside syntheses is reported. Additionally to the original Cerny route, haloethyl thioglycosides are also prepared in stepwise procedures from glycosides (I) or trityl 1-thioglycosides. This new type of leaving
group in glycoside syntheses shows excellent reactivity and good selectivity. —
