Alkylations with 2-octyl iodide of carbanions generated in THF by LDA from d- aminonitriles or protected cyanohydrines occur with inversion of configuration and an important racemization ; these reactions do not involve radical intermediates. En d&pit de l'importance synthetique des alkylations de
We describe an efficient synthesis of methyl 6-halogeno-6-deoxyglycosides which was performed using Ph$-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 E&d
