Intramolecular pauson-khand reactions of methylenecyclopropane and bicyclopropylidene derivatives as an approach to spiro(cyclopropanebicyclo[n.3. 0]alkenones)

Intramolecular Pauson-Khand reactions of methylenecyclopropane and bicyclopropylidene were performed to develop spiro(cyclopropanebicyclo[n.3.0] alkenones. Pauson-Khand reactions of the methylenecyclopropane derivatives with a substituent on the ring as w

A sterically-encumbered, C2-symmetric chiral acetal for enhanced asymmetric induction in the Pauson-Khand reaction

High levels of diastereoselection were achieved in the PKR, of 1,6- and 1,7-cyclopropylidenynes bearing a bulky propargylic C2-symmetric acetal.

Enantioselective Construction of Spirooct-1-en-3-ones>

Intramolecular Pauson-Khand reactions of 1,6-enynes 3a-c with a methylenecyclopropane terminator and a chiral acetal moiety adjacent to the triple bond gave spiro 5a-c in good yields with a diastereoselecti
