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

A ready method for generating oxycarbinyl radicals for conjugate-addition-alkylation or radical cyclization reactions

A ready method is described from generating oxycarbinyl radicals from alcohols, acetals and aldehydes which involves periodic addition of di-tert-butyl-hyponitrite (DBH) to a refluxing solution of the precursor.The resulting radicals may be trapped intermolecularly by α-enones in conjugate-addition-alkylation reactions, or intermolecularly in ring-forming reactions.Typically, small portions of DBH are added every 10-15 minutes until the reactant of interest has been consumed.

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
