摘要：

Treatment of (eta(4)-2-alkoxy-4-vinyl-2,5-dihydrofuran)-Fe(CO)(3) complexes 1 and 2 with nucleophiles in the presence of Lewis acids leads to exo-products of type 4 with high diastereoselectivity. Acidic hydrolysis gives hydroxy aldehyde complexes 3. Racemization, which seems to occur at the stage of intermediary cations of type 5, can be suppressed by proper choice of reaction conditions.
