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.
