A palladium catalytic system is reported for the divergent tandem cycloisomerization and cross-coupling of carbonyl- and imine-tethered alkylidenecyclopropanes (ACPs). The selection of ancillary ligands is pivotal for the interception of the heteropalladacyclic intermediates with different external nucleophiles.

A novel procedure for the synthesis of cis-bicyclic spirocyclopropanelactones from cyclopropylidenyl aldehydes via the molybdenum-mediated cyclocarbonylation is described. The use of (C7H8)Mo(CO)3 with DMSO to promote the reaction results in an efficient and convenient protocol for the three-component assembly in high yields.
