dihydroxylation of the terminal olefin of nonconjugated diene 7 using the Sharpless AD-mix reagent. The precursor to 16, (E,Z)-stannyl diene ester 13, was assembled with high selectivity in a single operation using a tandem syn-addition of tributyltin cuprate to acetylene followed by conjugateaddition to ethyl propiolate. Structural variants 2 and 3 were assembled using palladium-catalyzed Sonogashira
