The synthesis of γ-alkylidene α,β-unsaturated δ-lactones was achieved by ring-closing metathesis of acrylates derived from (1,3-butadien-2-yl)methanols. The application to the synthesis of the C1-C8 subunit of biselide E is reported.

The scope and limitations of Pd(0)-catalyzed intramolecular coupling of amino-tethered vinyl halides and ketone enolates as a methodology for the synthesis of nitrogenheterocycles have been studied. This reaction constitutes a synthetic procedure to obtain bridged, condensed, and monocyclic nitrogen-containing compounds.
