Application of dehydroabietic acid in palladium-catalysed enyne cycloisomerisationWu, Na, Li, R., Cui, F., Pan, Y. 26 May 2020 (has links)
Yes / Dehydroabietic acid (DAA) promotes palladium(0)‐catalysed cyclisations of arene‐tethered 1,7‐enynols and 1,m‐enynoates (m=6,7) to give fused carbocyclic dienes. 6,6,6,5‐Tetracyclic lactones are accessible by one‐pot cycloisomerisation/Diels–Alder reaction/lactonisation from 1,7‐enynols. Furthermore, asymmetric counteranion‐directed catalysis has been developed, which afforded an indene derivative with an all‐carbon quaternary stereogenic center. / NSFC.
