[reaction: see text] Bicyclo[4.3.0]nonanes (hydrindanes) and bicyclo[3.3.0]octanes (octahydropentalenes) are easily synthesized by palladium-catalyzed cycloalkenylations. Additionally, benzo-fused bicyclo[3.3.0]octanes are prepared for the first time through intramolecular coupling between silyl enol ethers and aromatic rings in the presence of catalytic palladium acetate.

A method for the opening of cyclopropyl ketones with samarium(II) iodide followed by the intramolecular trapping of an electrophile is described. This process leads to the obtainment of functionalized spirocyclic, bicyclic, and tricyclic ketones in moderate to good yields.

product (±)‐goniomitine was synthesized by a method featuring two key steps: 1) fragment coupling to a functionalized cyclopentene by a novelpalladium‐catalyzed decarboxylative vinylation reaction and 2) an unprecedented one‐pot integrated oxidation/reduction/cyclization (IORC) process to convert the substituted cyclopentene into the tetracyclic skeleton of goniomitine with high chemo‐, regio‐, and diastereoselectivity

Photolysis of 3-(3-methylbut-3-enyl)cyclopent-2-enone (4) leads to the tricyclo [5.2.0.01,5]nonane (5); the derived diazoketone (7) undergoes Wolff rearrangement to give esters (8) and (9), derivatives of tricyclo [4.2.0.01,4]octane (1).
