  Pd0/SnII mediated three-component cascade coupling (3-C3) approaches

  摘要：

  The 3-C(3)strategy involves (i) Pd(0)/SnX2 (X = Cl, Br) mediated generation of allyltin(IV) from allyl bromide in anhydrous DCM, (ii) formation of homoallyloxytin(IV) intermediate I from allyltin(IV) and an aldehyde, and (iii) coupling of I with an aldehyde, an aryl epoxide or an arene as the third partner to afford tetrahydropyrans, benzyl tetrahydropyrans or 4,4-diaryl-but-1-enes, respectively.

• Nickel-catalyzed arylative substitution of homoallylic alcohols

  Direct coupling of unactivated alcohols remains a challenge in synthetic chemistry. Current approaches to cross-coupling of alcohol-derived electrophiles often involve activated alcohols such as tosylates or carbonates. We report the direct arylative substitution of homoallylic alcohols catalyzed by a nickel-bisphosphine complex as a facile method to generate allylic arenes. These reactions proceed

  未活化醇的直接偶联仍然是合成化学中的一个挑战。目前醇衍生亲电子试剂交叉偶联的方法通常涉及活化醇，例如甲苯磺酸盐或碳酸盐。我们报道了由镍-双膦配合物催化的高烯丙醇的直接芳基化取代，作为生成烯丙芳烃的简便方法。这些反应通过形成烯丙醇中间体进行。随后用芳基环硼氧烷亲核试剂进行烯丙基取代，能够形成多种烯丙基芳烃。对甲氧基苯基硼酸的存在对于活化烯丙醇以实现高产物收率至关重要。
• Catalytic Stereospecific Allyl–Allyl Cross-Coupling of Internal Allyl Electrophiles with AllylB(pin)

  DOI：10.1021/ol500456s

  日期：2014.4.18

  Application of internal electrophiles in catalytic stereospecific allyl allyl cross-coupling enable the rapid construction of multisubstituted 1,5-dienes, including those with all carbon quaternary centers. Compounds with minimal steric differentiation can be synthesized with high enantiomeric excess.
