SeO2-Mediated Oxidative Transposition of Pauson-Khand Products

Oxidative transpositions of bicyclic cyclopentenones mediated by selenium dioxide (SeO2) are disclosed. Treatment of Pauson-Khand reaction (PKR) products with SeO2 in the presence or absence of water furnishes di- and trioxidized cyclopentenones, respectively. Mechanistic investigations reveal multiple competing oxidation pathways that depend on substrate identity and water concentration. Functionalization of the oxidized products via cross-coupling methods demonstrates their synthetic utility. These transformations allow rapid access to oxidatively transposed cyclopentenones from simple PKR products.

Cationic rhodium(I)-dppf complex-catalyzed olefin isomerization/propargyl claisen rearrangement/carbonyl migration cascade

(Chemical Equation Presented) We have established that a cationic rhodium(I)-dppf complex catalyzes isomerizations of allyl propargyl ethers to allenic aldehydes in good yields from room temperature to 40°C. On the other hand, carbonyl migration reactions
