Rapid Generation of Molecular Complexity in the Lewis or Brønsted Acid-Mediated Reactions of Methylenecyclopropanes
TL;DR: Lewis and Brønsted acids can be used as catalysts or reagents in the reactions of MCPs with a variety of substrates, and substituents on the terminal methylene or on the cyclopropyl ring of M CPs significantly affect the reaction pathways.

A gold-catalysed enantioselective Cope rearrangement of achiral 1,5-dienes
TL;DR: A gold(I) catalyst is shown to induce an asymmetric Cope rearrangement of achiral 1,5-dienes containing a cyclopropylidene moiety to produce vinylcyclopropanes in high yield and good to excellent enantioselectivities.
