✦ Synopsis

The Pd(0) and Pd(II)-catalysed cyclisafion/functionalisation reactions of acyclic carbohydrate-derived 1, ldiacetuxy-2,7-dienΒ’ and l,l-diacctoxy-2-Β’n-7-ynΒ’ compounds ptecccded in a s~reospccific fashion to furnish chiraL multi-functionalised furanoid and cyclopontanoid products. The products contained valuable enolacctatΒ’ moieties. which can be further daborated to enable the facile entry to an array of substituted five membered ring compounds.
