  • Stereoselective Benzannulations and Cyclohexadienone Annulations of Fischer Carbene Complexes in the Synthesis of Decala-2,4-dien-1-ones and in the Synthesis of Tetralin Chromium Tricarbonyl Complexes
    作者:Richard P. Hsung、William D. Wulff、Cynthia A. Challener
    DOI:10.1055/s-1996-4292
    日期:1996.6
    The first general study is reported on the stereoselectivity of the benzannulation reaction involving diastereoselection at the planar center of chirality of the newly formed arene ring complexed to chromium that is induced from a chiral carbon center on the carbene complex. The stereochemistry of a number of 5- and 8-substituted tetralin chromium tricarbonyl complexes, which are produced from the benzannulations of cyclohexenyl carbene complexes with chiral centers at the 3- and 6-position, is determined. These results are compared with the stereochemistry of the formation of 5,9- and 8,9-disubstituted decala-2,4-dien-1-ones produced from the reactions of the same carbene complexes bearing an additional substituent in the 2-position of the cyclohexenyl ring. The benzannulation reaction is most selective with 3-substituted cyclohexenyl carbene complexes giving predominately the anti-isomer of the 8-substituted tetralin chromium tricarbonyl complexes. In contrast, the cyclohexadienone annulation is most selective with 6-substituted cyclohexenyl carbene complexes giving predominantly the trans-isomer of the 5,9-disubstituted decala-2,4-dien-1-ones. A mechanistic accounting of the stereochemical results is proposed which is predicated on three assumptions: 1) that the η 1,η 3-vinyl carbene complexed intermediate is in equilibrium, 2) vinyl ketene complex formation is irreversible and occurs with a carbon monoxide migration that is in concert with coordination of the double bond of the cyclohexene ring, and 3) the electrocyclic ring closure of the vinyl ketene complex is stereospecific.
    首次报道了关于苯并化反应立体选择性的综合研究,该反应涉及在新形成的手性芳环平面中心处的立体选择性,该芳环与络合,其手性源自卡宾络合物的手性碳中心。确定了从3-和6-位具有手性的环己烯基卡宾络合物苯并化反应生成的若干5-和8-取代的四氢三羰基络合物的立体化学。这些结果与从相同卡宾络合物(环己烯环的2-位具有额外取代基)反应生成的5,9-和8,9-二取代的癸-2,4-二烯-1-酮的立体化学形成进行了比较。苯并化反应在3-取代的环己烯基卡宾络合物中显示出最高的立体选择性,主要生成8-取代的四氢三羰基络合物的反式异构体。相比之下,环己二烯酮并环反应在6-取代的环己烯基卡宾络合物中最具选择性,主要生成5,9-二取代的癸-2,4-二烯-1-酮的顺式异构体。提出了一个基于三个假设的机理性解释来解释立体化学结果:1) η1, η3-乙烯基卡宾络合物中间体处于平衡状态,2) 乙烯基烯酮络合物形成是不可逆的,并且伴随着一氧化碳迁移,这与环己烯环双键的配位同时发生,3) 乙烯基烯酮络合物的电环闭环反应是立体专一性的。

    Isoxazoles substituted with an electron-withdrawing group at the 4-position undergo electrochemical and yeast-catalysed N–O bond cleavage. The electrolysis is much more efficient and, with acyl- and alkoxycarbonyl-substituted isoxazoles, it affords the enolised dicarbonylimine functionality characteristic of the herbicide Grasp®. Regioisomeric 4- and 5-substituted isoxazoles are accessible through nitrile oxide cycloaddition chemistry, using halogen as a steric auxiliary to control the regiochemistry of reaction. Crystal data for compounds 11 and 19b are presented.
