Efficient generation of β-L-rhamnosidic linkages by the 2-ulosyl donor approach: Synthesis of a trisaccharide with a central β-L-rhamnose unit

Practical procedures for the production of variously blocked 6-deoxy-α-L-arabino-2-ketohexosyl bromides from L-rhamnose have been developed. These compounds are highly useful as indirect β-L-rhamnosyl donors: they undergo β-specific glycosidations under Koenigs-Knorr conditions, and the 2-keto group of the resulting 6-deoxy-β-L-hexosiduloses is reduced with high β-L-rhamno selectivity. The straightforward application of this 2-ulosyl donor approach for the synthesis of β-L-rhamnose-containing di- and trisaccharides is demonstrated. ( Wiley-VCH Verlag GmbH & Co.

Efficient generation of β-L-rhamnosidic linkages via the ulosyl bromide approach
Lichtenthaler, Frieder W.,Metz, Thomas W.
, p. 5477 - 5480 (2007/10/03)
Practical protocols have been developed for the acquisition of ulosyl bromides of type III from L-rhamnose, i.e. 6-deoxy-α-L-arabino-2-ketohexosyl bromides 6-8. They have high potential as indirect β-L-rhamnosyl donors, as they undergo β-specific glycosid
