Construction of Cyclopenta[ b]pyridine Frameworks via Pd(0) π-Lewis Base-Initiated Cascade Reaction of Enyne-Tethered Malononitriles
{{output}}
A Pd(0) π-Lewis base-initiated cascade transformation of 1,3-enyne-tethered malononitriles is disclosed, proceeding through intramolecular vinylogous addition of the nucleophilicity-enhanced alkyne moiety to a pendent cyano group, cis/trans isomerization, and... ...
