Gold(I)- and Yb(OTf)<sub>3</sub>-Cocatalyzed Rearrangements of Epoxy Alkynes: Transfer of a Carbonyl Group in a Five-Membered Carbocycle

We report here the intramolecular reactions between α,β‐epoxy ketones and alkynes cocatalyzed by gold(I) and Yb(OTf)3. This new catalytic system based on a combination of gold(I) and Yb(OTf)3 allows facile transformation of epoxy alkynes to give novel indene derivatives in moderate to good yields under mild conditions. Moreover, we describe here the first observation of a transfer of a carbonyl group

Developments are reported in the catalytic synthesis of biaryls containing an ortho-carbaldehyde or 6H-dibenzopyrans in the presence of palladium/norbornene as catalyst. The reaction of o-substituted aryl iodides and o-bromobenzyl alcohols proceeds by unsymmetrical aryl-aryl coupling to form a seven-membered oxapalladacycle intermediate, which may undergo an intramolecular redox process to form carbonyl groups or a C-O coupling to six-membered cyclic ethers. The predominant formation of di-benzopyrans as well as of biaryl structures containing the oxidized CHO group in one ring and the reduced CH2OH in the other is described along with some mechanistic insights.

The total stereoselective synthesis of (Z)-rubrenoic I (1a), (Z)-nor-rubrenoic I (17a), (E)-rubrenoic III (3b), and nor-(E)-rubrenoic III (30b) acids was achieved using Suzuki and Stille cross-coupling reactions from readily available starting materials.
