mixture of Zn, CeCl3, 3-bromo-1-tributylstannylpropene and aldehyde or ketone in THF/PhH ( was sonicated in a commercial cleaning bath. δ-Tributylstannylhomoallyl alcohol was produced as the sole regioselective product and (E)-stereoisomer was formed as major adduct. Silyl Misoprostol was synthesized by the coupling reaction of cyclopentenone and stannylhomoallyl alcohol.
