A prostaglandin B1(PGB1) analog and PGB1 methyl ester were synthesized by the palladium-catalyzed stepwise cross-coupling reaction of (E)-(2-bromoethenyl)diisopropoxyborane with (1-methoxy-1-hexenyl)zinc chloride and 3-bromo-2-cyclopenten-1-one derivatives. According to this method, the skeleton of PGB1 is prepared by the one-pot operation without isolation of any intermediates.
