    摘要:
    我们重新研究了 2-甲基环己酮与 3-戊烯-2-酮的罗宾逊环化反应。与之前的结果不同,研究发现反应产物不仅产率低,而且在生成顺式-4,4a-二甲基-4,4a,5,6,7,8-六氢萘-2(3H)-酮(3a)及其反式异构体(3b)时,溶剂决定的立体选择性也比报道的低得多。正如预期的那样,在环化过程中还生成了 4β,8α-二甲基-4,4aβ,5,6,7,8-六氢萘-2(3H)-酮和 4β,8β-二甲基-4,4aα,5,6,7,8-六氢萘-2(3H)-酮这两种区域异构体。在与 4-苯基-3-戊烯-2-酮的反应中也观察到类似的趋势。此外,还通过另一种方法合成了环化产物 3a、3b、顺式-4-苯基-4a-甲基-4,4a,5,6,7,8-六氢萘-2(3H)-酮和反式-4-苯基-4a-甲基-4,4a,5,6,7,8-六氢萘-2(3H)-酮。

    treatment with sulfuric acid–methanol (1:1) at 0 °C. As the major product, 1-methylbicyclo[5.3.0]dec-6-en-8-one was produced from 2-methylcycloheptanone. Remarkable regioselective cyclopentannulation was observed in 2-methylcyclohexanone and 2,3-dimethylcyclohexanone wherein 1-methyl- and trans-1,2-dimethyl-substituted bicyclo[4.3.0]non-5-en-7-one (BNO) are produced, respectively. With 3-butyn-2-ol, 2-methylcyclohexanone
    描述了一种高度区域和立体选择性的五元环环化,涉及酮的炔丙醇二阴离子加合物的酸处理。通过在 0°C 下用硫酸-甲醇 (1:1) 处理,2-辛酮的炔丙醇加合物转化为 2-甲基-3-戊基-2-环戊烯酮。作为主要产物,1-甲基双环[5.3.0]dec-6-en-8-one由2-甲基环庚酮生产。在 2-甲基环己酮和 2,3-二甲基环己酮中观察到显着的区域选择性环戊环化,其中产生了 1-甲基-和反式-1,2-二甲基取代的双环 [4.3.0] 非 5-en-7-one (BNO) , 分别。使用 3-butyn-2-ol,2-甲基环己酮被转化为顺式 1,9-二甲基取代的 BNO。4-异丙基-2-甲基环己酮转化为83-85:17-15的c-3-异丙基-γ-1混合物,c-9-二甲基-BNO 及其 3-差向异构体。这些结果用热力学上最有利的羟基戊二烯基阳离子中间体的旋转闭环来解释。3...

    established that the reactants complex has a chairlike geometry. In all the examples, the diastereoselectivity is superior to 98%. The enantioselectivity of the reactions is excellent as is usually the case with unsubstituted electrophilic olefins, the example with phenyl methacrylate being particularly remarkable (de and ee >99%). In each case the favored diastereofacial selectivity is again in accordance

  • A Reexamination of the Robinson Annelation of 2-Methylcyclohexanone with 3-Penten-2-one and 4-Phenyl-3-buten-2-one
    作者:Mitsuko Kikuchi、Akira Yoshikoshi
    DOI:10.1246/bcsj.54.3420
    日期:1981.11
    The reported Robinson annelation of 2-methylcyclohexanone with 3-penten-2-one has been reexamined. In contrast to the previous result, it was found that the reaction product was not only obtained in a low yield, but also the solvent-depending stereoselectivity in the formation of cis-4,4a-dimethyl-4,4a,5,6,7,8-hexahydronaphthalen-2(3H)-one (3a) and its trans isomer (3b) was considerably lower than that reported. As expected, regioisomers, 4β,8α-dimethyl-4,4aβ,5,6,7,8-hexahydronaphthalen-2(3H)-one and 4β,8β-dimethyl-4,4aα,5,6,7,8-hexahydronaphthalen-2(3H)-one, were also formed in the annelation. A similar tendency was observed in the reaction with 4-phenyl-3-penten-2-one. The annelation products, 3a, 3b, cis-4-phenyl-4a-methyl-4,4a,5,6,7,8-hexahydronaphthalen-2(3H)-one, and trans-4-phenyl-4a-methyl-4,4a,5,6,7,8-hexahydronaphthalen-2 (3H)-one, were also synthesized by an alternative route.

  • Enantioselective synthesis of (+)-de-isopropenyl nootkatone
    作者:Nathalie Dahuron、Nicole Langlois
    DOI:10.1016/s0957-4166(00)80430-9
    日期:1993.8
    The absolute configuration of the delta-oxo acid 11, obtained through an asymmetric Michael-type reaction involving the activated chiral alpha,beta-unsaturated oxazoline 7, was established by comparison of the CD curves of the derived (+)-octalone 14 and (+)-nootkatone 15.
