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.
揭示了具有以下结构的化合物:
其中R21是烷基、芳基、烷氧基、羟基、氨基或卤素原子;其中R2是氢或烷基、芳基、烷氧基或氨基;其中R23和R24分别独立地选自氢、烷基、芳基、烷氧基、羟基、氨基和卤素原子,或者R23和R24与它们所连接的碳原子一起形成环;其中R25是氢、烷基、芳基、烷氧基、羟基、O-硅基或卤素原子;其中Z与其连接的碳原子一起形成一个5-12环;Y是一个电子吸引基团。这些化合物可用于制备erogorgiaene同系物,如erogorgiaene、pseudopterosin A、helioporin E、pseudopteroxazole、colombiasin A、elisapoterosin B、elisabethadione、p-苯醌天然产物、ileabethin、sinulobtain B、sinulobtain C和sinulobtain D。
