Synthesis of active principles from the leaves of Moringa oleifera using S-pent-4-enyl thioglycosides

Leuck, Michael,Kunz, Horst

, p. 33 - 44 (1998)

α-l-Rhamnosides of 4-hydroxy-benzyl compounds with nitrile, carbamate, and thiocarbamate groups occurring in Moringa oleifera leaf extracts and the α-l-rhamnoside of anisaldehyde derivatives were synthesised. Electrophilic activation of S-pent-4-enyl thiorhamnosides was applied for the construction of glycosidic linkages. Copyright (C) 1997 Elsevier Science Ltd.
