Synthesis of substituted allyl acetates from heterocyclic dienes by a Pd-promoted arylation-acetoxylation cascade

Abstract

Pd-catalysed arylation-acetoxylation cascade, a previously reported methodology, was applied in the functionalisation of unsymmetrical dienes. Both explored classes of compounds, isoquinoline and ss-carboline-derived dienes, afforded single regioisomers. Although further improvements of the process are necessary, primarily due to lower yields, the described functionalisation of the studied compounds might be useful in the synthesis of emetine and related naturally occurring compounds.
