An efficient approach to synthesize Δ6-estrogens is described. The key steps in the synthesis are the introduction of a hydroxyl group at the Δ6 position of a suitably protected estrogen using a superbase and subsequent dehydration with Martin sulfurane reagent or methyltriphenoxyphosphonium iodide. The two-step synthetic procedure readily gave the Δ6-estrogens in high yield.
