    摘要: Disclosed are compounds having the formula: wherein R21 is an alkyl, aryl, alkoxy, hydroxy, or amino group or a halogen atom; wherein R2 is hydrogen or an alkyl, aryl, alkoxy, or amino group; wherein R23 and R24 are independently selected from hydrogen, an alkyl, aryl, alkoxy, hydroxy, or amino group, and a halogen atom or wherein R23 and R24, taken together with the carbon atom to which they are bound, form a ring; wherein R25 is hydrogen, an alkyl, aryl, alkoxy, hydroxy, or O-silyl group or a halogen atom; wherein Z, taken together with the carbons to which it is bonded, forms a 5-12 membered ring; and wherein Y is an electron withdrawing group. These compounds can be used to prepare erogorgiaene congeners, such as erogorgiaene, pseudopterosin A, helioporin E, pseudopteroxazole, colombiasin A, elisapoterosin B, elisabethadione, p-benzoquinone natural products, ileabethin, sinulobtain B, sinulobtain C, and sinulobtain D.
