, p. 6519 - 6522 (2007/10/03)
The combination of a zinc-copper mediated conjugate addition-cyclization, an intramolecular [2 + 2] photocycloaddition, and a radical fragmentation reaction provides access to a variety of medium ring fused carbocyclic systems in good overall yields.
Addition of functionalized zinc copper reagents to acetylenic esters: Synthesis of 2-carboalkoxy cyclohexenones
