The conversion of 2-butyn-1,4-diol to (Z)-2,4-diiodobut-2-en-1-ol proceeded efficiently using in situ generated trimethylsilyl iodide. Coupling with Grignard reagents and other nucleophiles delivered (2Z)-2-iodo allylicalcohols. The geometry of the products was established by nOe.
Cross-conjugated dienols 3 were satisfactorily obtained via the palladium-catalyzed coupling reaction of 2-iodo-2-alken-1-ol 6 with vinyl Grignard reagents.
