Thefirst method for the asymmetric synthesis of C3-monosubstitutedchiral carbazolones, structural motifs common in medicinal chemistry,has been achieved using Pd-catalyzed decarboxylative protonation ofcarbazolones. This methodology has been applied to the first catalyticenantioselective formal synthesis of (−)-aspidofractinine withstep economy and simplicity. [ABSTRACT FROM AUTHOR]

The first catalytic enantioselective formal synthesis of (-)-aspidofractinine (II) is achieved via key intermediate (I), which is synthesized in only ten steps from commercially available starting materials. [ABSTRACT FROM AUTHOR]

A novel catalytic enantioselective synthesis of functionalized 1,3-enynes has been developed featuring the design and synthesis of conjugated nitro dienynes as a useful new class of Michael acceptors. Moreover, a simple, yet flexible catalytic cascade approach to functionalized enantioenriched acyclic α,β-enones and cyclic dienones has also been developed. [ABSTRACT FROM AUTHOR]

The article presents chemical equations related to an article on catalytic asymmetric synthesis of 1,3-enyne scaffolds and its design and synthesis of conjugated nitro dienynes by X. Li and others, published in the journal "Chemical Communication" in 2014.
