gram quantities via addition of furan to methyl vinyl ketone. Structure 13 was then treated with ethynylmagnesium bromide to afford propargyl alcohol 14 in 94% yield. Copper-catalyzed hydroboration of 14 generated vinyl boronate ester 15, 22 which was coupled to enone 16 using Pd2dba3, dppf, and aq. K3PO4 (2 M) as a catalyst system. This simple cross-coupling reaction furnished 9a in 88% overall yield from 14.
