Abstract
Both diastereoisomers of 1,4-dimethyl-2,8-dioxabicyclo[3.2.1]. octane-4-cab oxylic acid ester (3, 4) and the 4-hydroxy methyl analogaes (5, 6) were syn thesised from ethyl acetoacetate and diethyl malonate respectively. The key step of these process involved intramolecular cyclisation using palladium chloride as catalyst.
