  • Further Explorations into the Synthesis of Dehydro<i>-Hedione</i><sup>®</sup>
    作者:Béat Winter、Christian Chapuis、Robert Brauchli、Jean-Yves de Saint Laumer

    日期:2013.2
    Reformatsky reaction with enone methyl ether 3b, followed by acidic workup of the crude reaction mixture. Alternatively, epoxidation (3‐chloroperbenzoic acid, CH2Cl2, 84% yield) of the tertiary allyl alcohol derivative 4 affords a 1 : 2 mixture of 8a and 8b. The latter epoxy ester 8b may also be obtained stereoselectively either from 4 (tBuO2H, [Mo(CO)6], 1,2‐dichloroethane, 70°, 62% yield; or tBuO2H, [VO(acac)2]
    脱氢己二酮(DHH)1可以通过与烯酮甲基醚3b的Reformatsky反应,然后对粗反应混合物进行酸性后处理,以20%的总收率获得。另外,叔烯丙醇生物4的环氧化(3-苯甲酸,CH 2 Cl 2,产率为84%)得到8a和8b的1:2混合物。后者的环氧酯8b也可以从4(t BuO 2 H,[Mo(CO)6 ],1,2-二氯乙烷,70°,62%收率;或t BuO 2H,[VO(acac)2 ],癸烷,20°,产率92%),或从5开始(AcOMe,LiN(SiMe 3)2,THF,-78°,84-87%)。BF 3 ⋅Et 2 O形催化级联重排和OH消除8A得到选择性DHH 1以88%的产率。气味较弱的己二酮类似物2b和2c的侧链的顺式排列是通过环氧或环丙烷部分来维持的。

    A substituted cyclopentanone represented by the following formula (2): (wherein R 3 and R 4 represent a substituent having 1 to 8 carbon atoms, may be the same as R 1 and R 2 , respectively, and may be the same as each other) can be produced by hydrogenating the double bond in a compound represented by the following formula (1): (wherein R 1 and R 2 represent a substituent having 1 to 8 carbon atoms) in the presence of a transition metal catalyst by using a carboxylic acid or a specific concentration of a carboxylic acid ester as a solvent. This process can produce a substituted cyclopentanone which is useful as a jasmine fragrance, an intermediate thereof or the like, in a simple and inexpensive manner at a high cis-isomer ratio.
