    摘要:
    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,叔烯丙醇衍生物4的环氧化(3-氯过苯甲酸,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 catalyst system, [Rh(COD)Cl]2–BINAP–AgSbF6, has been developed as a second-generation catalyst for the cycloisomerization of 1,6-enynes tethered by carbon chains. Cyclopentanes and cyclopentanones, which can contain functional groups, such as the 1,4-dienes, vinyl ether, aldehyde etc., were obtained from readily available starting materials in high yields and selectivities. Both regioselectivities and enantioselectivities are excellent: only 1,4-dienes were observed and in over 99% ee.
