Synthese de nouveaux tensioactifs glycosidiques par l'intermediaire de sucres halogenes. Thioethers et sulfones derives de l'α-d-glucoside et l'α-d-mannoside de methyle.
摘要:
We describe an efficient synthesis of methyl 6-halogeno-6-deoxyglycosides which was performed using Ph3P-X2 in DMF solution. Carbohydrate halides could thus be isolated in high yields without preliminary protection of the secondary hydroxyl groups, and were used as intermediates for the preparation of 6-alkylthio- and 6-alkylsulfonyl-6-deoxy glycosides. These derivatives are new non-ionic chiral surfactants.
