π-Allyl cation cyclisations initiated by silver(I)-promoted electrocyclic ring opening of ring-fused gem-dibromocyclopropanes possessing tethered nucleophiles: the influence of chiral auxiliaries on the diastereoselectivity of cyclisations involving meso-substrates

Abstract

The epimeric pairs of ring-fused gem-dibromocyclopropanes 17/18 and 27/28, each of which possesses an internal plane of symmetry and has a tethered carbamate moiety with an associated chiral auxiliary, react with silver perchlorate to give, in a diastereoselective manner, the corresponding pairs of azabicyclic compounds, 19/20 and 29/30 respectively.
