Cycloaddition and one-carbon homologation studies in the synthesis of advanced iridoid precursors

A Diels-Alder cycloaddition approach to the sweroside aglycone intermediate of iridoids was explored using silylated butenolides and levoglucosenone as dienophiles under both Lewis acid and thermal conditions. Results of this study reveal no evidence that

Chiral Oxabicyclic Systems from Ribonolactone

We describe the synthesis of (-)-5-O-diphenyl-t-butylsiloxymethyl-5H-furan-2-one (4) from D-ribonolactone; conversion of this chiral butenolide into (+)-(1R,6S,7S)-7-diphenyl-t-butylsiloxymethyl-8-oxabicyclonon-3-en-9-one (10) (by means of a Diels-

Chiral Bicycles from Ribonolactone

The preparation of the chiral butenolide (4b) is described, together with its use in annulation reactions yielding stereochemically defined bicyclo, , and ring systems; the synthetic utility of these species is indicated.
