  Reductive aldol-type reaction of α,β-unsaturated esters with aldehydes or ketones in the presence of Rh catalyst and Et2Zn

  摘要：

  The reaction of RhCl(PPh3)(3) with Et2Zn easily generated a rhodium-hydride complex (Rh-H) that added to alpha,beta-unsaturated esters to form rhodium enolate complexes by formal 1,4-reduction. These rhodium enolates gave the corresponding Reformatslcy-type reagents through transmetalation, and they reacted with various aldehydes and ketones to give reductive aldol-type products in good to excellent yields.

  reactions) have been performed using novel chiral zirconium catalysts. The reactions proceeded in high yields under mild conditions, and anti-adducts were obtained in high diastereo- and enantioselectivities. The catalysts were first prepared from zirconium(IV) tert-butoxide (Zr(O(t)Bu)(4)), (R)-3,3'-diiodo-1,1'-binaphthalene-2,2'-diol ((R)-3,3'-I(2)BINOL), a primary alcohol, and a small amount of water.

  甲硅烷基烯醇醚与醛的催化不对称醛醇反应（Mukaiyama 醛醇反应）已使用新型手性锆催化剂进行。反应在温和条件下以高产率进行，并以高非对映选择性和对映选择性获得抗加合物。该催化剂首先由叔丁醇锆 (IV) (Zr(O(t)Bu)(4)), (R)-3,3'-diiodo-1,1'-binaphthalene-2,2'-二醇 ((R)-3,3'-I(2)BINOL)、伯醇和少量水。结果表明，伯醇在完成催化循环中起着重要作用，少量的水对于获得高选择性至关重要。此外，手性锆催化剂的活性通过使用新的配体 (R)-3,3'-I(2)-6,6'-X(2)BINOL (X = Br, I, C(2) F(5)), 并且已经表明，使用新型锆催化剂，即使是反应性较低的底物的羟醛反应也能顺利进行。最后，对这些催化剂进行了核磁共振研究，这表明催化剂会形成二聚体结构，水会影响催化剂的形成。

  The concept of Lewis base activation of Lewis acids has been reduced to practice for catalysis of the aldol reaction of silyl ketene acetals and silyl dienol ethers with aldehydes. The weakly acidic species, silicon tetrachloride (SiCl4), can be activated by binding of a strongly Lewis basic chiral phosphoramide, leading to in situ formation of a chiral Lewis acid. This species has proven to be a competent

  olefinic aldehydes as well as aliphatic aldehydes (albeit more slowly) with excellent enantioselectivity. The homologous tert-butyldimethylsilyl ketene acetal of tert-butyl propanoate adds with nearly exclusive anti diastereoselectivity to a similar range of aldehydes also with excellent enantioselectivity. The origin of the slower reaction rate with aliphatic aldehydes is revealed to be the formation of chlorosilyl
