An efficient and selective synthesis of nakienone A involving a novel protocol for α-alkenylation of ketones via palladium-catalyzed alkenyl-alkenyl coupling
摘要:
Nakienone A was synthesized for the first time from 3-methoxy-2-cyclopentenone, dienyl iodide 7, and LICH(2)OMOM in 8 steps in 26% overall yield with full control of the alkene geometry using the Pd-catalyzed cross coupling reaction of a cyclopentenylzinc derivative 6a with 7 as a key step.
