Synthesis of α-bromoisolevoglucosenone and its cyclopenta annulation

4,4-Dimethyl-3-nitro-10,11-dioxatricyclo[6.2.1.02,6]undec-5-en-7-one possessing a bicyclic iridoid skeleton was synthesized in two steps from isolevoglucosenone which was obtained in turn from levoglucosenone through 4-benzyloxy-2-tosyloxy deri

Convergent synthesis of (1→2)- and (1→4)-C-linked imino disaccharides

A convergent synthesis of (1→2)- and (1→4)-C-linked imino disaccharides was achieved by applying Nozaki-Kishi coupling of a hydroxyproline-derived carbaldehyde with isolevoglucosenone or levoglucosenone derived enol triflates.

Synthesis of 1,6-Anhydro-2-chloro-2,3,4-trideoxy-β-D-erythro-hex-3-enopyranose and its Stereospecific SN2' Substitution

The chlorination of 1,6-anhydro-3,4-dideoxy-β-D-threo-hex-3-enopyranose (2) with SOCl2 and pyridine gives predominantly 1,6-anhydro-2-chloro-β-D-erythro-hex-3-enopyranose (3).The chloride (3) takes place exclusively the suprafacial SN2' substit

Clay montmorillonite in carbohydrates : Use of 'claysil' as an efficient heterogenous catalyst for the intramolecular Ferrier reactions leading to 1,6-anhydro rare saccharides

Clay montmorillonite supported silver reagent - claysil - was prepared and advantageously used in the intramolecular Ferrier reaction of 6-hydroxy glycals 1a-9c. The unsaturated sugars 13a-21c so obtained were stereoselectively hydroxylated leading to the

Synthesis of 1,6-anhydro-2,3-dideoxy-β-D-erythro- and -threo-hex-2-enopyranose from 3,4-di-O-substituted glycals by a facile intramolecular Ferrier reaction

The 1,6-anhydro-2,3-dideoxy-β-D-erythro- 7-9 and -threo-hex-2-enopyranoses 10-12 are valuable synthons for the preparation of structurally diverse natural products. This paper reports on a new, general, and efficient route to their synthesis from 3,4-di-O
