  镍催化的5 -Endo-Trig环化反应使烯类不对称加氢芳基化

  摘要：

  镍催化的烯酮的还原环化在高对映异构体诱导下提供了多种茚满酮。该反应具有前所未有的广泛底物范围。新方法的多功能性在医学上有价值的（R）-托特罗定，母体和氘代（+）-茚达林以及抗肿瘤天然产物（+）-multisianthol的几种短时立体选择性合成中得到了证明。相比之下，这些化合物不能通过钯催化的类似方法令人满意地制备。

• Total synthesis of (±) mutisianthol and (±) epi-mutisianthol via intramolecular oxidative Heck cyclization approach

  A simple and straight forward synthesis of (±) mutisianthol and its epimer is described. Implementation of 4-pentenal derivative for palladium catalyzed intramolecular 5-endo-trig Heck cyclization is effective. Other key steps involved are Wittig olefination with allyloxymethylenetriphenylphosphorane, [3,3] sigmatropic rearrangement and chemoselective reduction of double bond.

  The chiral bisphosphine dioxide-catalyzed asymmetric conjugate reduction of acyclic β,β-disubstituted α,β-unsaturated ketones with trichlorosilane affords saturated ketones having a stereogenic carbon center at the carbonyl β-position with high enantioselectivities. Because the E/Z-isomerizations of enone substrates occur concomitantly, reduction products with the same absolute configurations are obtained

  用三氯硅烷手性双膦二氧化物催化的无环β，β-二取代的α，β-不饱和酮的不对称共轭还原，可得到在羰基β-位具有立体碳中心且具有高对映选择性的饱和酮。因为烯酮底物会同时发生E / Z-异构化，所以从（E）-或（Z）-烯。由于其碳正离子稳定能力，在烯酮的β位上存在富电子芳基的情况下，共轭还原被加速。为了阐明观察到的对映选择性的起源，还进行了计算研究。实现了二烯酮的区域和对映选择性的还原，并将其应用于ar- turmerone，turmeronol A，mutisianthol和jungianol，它们是旋光的倍半萜烯的合成。
• A diastereoselective total synthesis of the sesquiterpene (±)-mutisianthol

  日期：2003.7

  The total synthesis of the phenolic sesquiterpene mutisianthol has been accomplished in 12 steps from the readily available 2-methylanisole. The required trans-1,3-disubstituted indan intermediate was obtained through a diastereoselective thallium(III) mediated ring contraction of a 1-methyl-1,2-dihydronaphthalene derivative.

  从容易获得的2-甲基苯甲醚以十二个步骤完成了酚倍半萜烯泛醇的全合成。所需的反式-1,3-二取代的茚满中间体是通过非对映选择性的（（III）介导的1-甲基-1，2-二氢萘衍生物的环收缩而获得的。

  The first synthesis of the natural product (+)-mutisianthol was accomplished in 11 steps and in 21% overall yield from 2-methylanisole. The synthesis of its enantiomer was also performed in a similar overall yield. The absolute configuration of the sesquiterpene (+)-mutisianthol was assigned as (1S,3R). Key steps in the route are the asymmetric hydrogenation of a nonfunctionalized olefin using chiral iridium catalysts and the ring contraction of 1,2-dihydronaphthalenes using thallium(III) or iodine(III). The target molecules show moderate activity against the human tumor cell lines SF-295, HCT-8, and MDA-MB-435.
• Structural Amendment and Stereoselective Synthesis of Mutisianthol

  日期：1997.5.1

  cis-1-(5-Acetoxy-3,6-dimethyl-1-indanyl)-2-methyl-1-propene synthesized from 3,6-dimethyl-1-indanone was found to be different from mutisianthol by spectral comparison. The presence of a high-field signal in the NMR spectrum of the final product and various intermediates, characteristic of the cis-1,3-dialkylindanes but absent in the spectrum of the natural terpene, suggests a revision of the structure of mutisianthol to the trans isomer. The trans-indane which was subsequently obtained indeed exhibits data fully agreeable with mutisianthol. A similar stereochemical revision for jungianol is also indicated.
