  Reductive Lithiation of Methyl Substituted Diarylmethylsilanes: Application to Silanediol Peptide Precursors

  摘要：

  Reductive lithiation of methyl-substituted diarylmethylsilanes using lithium naphthalenide represents a practical method for the preparation of the corresponding sillyl lithium reagents. Their addition to chiral sulfinimines affords versatile precursors to silanols and silanediols. The replacement of the currently used diphenylsilane motif by a more labile diarylsilane moiety allows the selective hydrolysis of one or two aryl groups by treatment with TFA.

• Catalytic enantioselective dehydrogenative Si–O coupling of oxime ether-functionalized alcohols

  (with silicon-stereogenic silanes) and enantioselective (with achiral silanes) Si–O couplings of azine donor-functionalized alcohols. The limitation, that is, the requirement of a nitrogen donor atom, prompted us to seek equally useful donor groups. Oxime ethers were identified as a suitable alternative, and we describe herein the preparation of a series of oxime ether-functionalized alcohols. To assess

  醇的不对称甲硅烷基化是解决其动力学拆分的一种不寻常但有效的方法，并且Cu-H催化的脱氢Si-O偶联特别值得注意，因为形成了二氢作为唯一的副产物。我们的实验室以前曾报道过对嗪供体官能化的醇进行非对映选择性（与硅-立体异构硅烷反应）和对映选择性（与非手性硅烷）Si-O偶联反应。这种局限性，即需要氮供体原子，促使我们寻求同样有用的供体基团。肟醚被确定为合适的替代物，并且我们在本文中描述了一系列肟醚官能化的醇的制备。为了评估其动力学分辨率中的不同取代模式，这些在使用硅固相硅烷的试剂控制的Si-O偶联中进行了测试。

  The photocatalyzed synthesis of silanols from tertiary si­lanes has been carried out using eosin Y under air. This is a metal-free method that uses a low catalyst loading, atmospheric oxygen as the oxidant, and visible-light conditions (blue light).

• Regioselective Rh(I)-Catalyzed Sequential Hydrosilylation toward the Assembly of Silicon-Based Peptidomimetic Analogues
  作者：Geanna K. Min、Troels Skrydstrup

  DOI：10.1021/jo300904z

  日期：2012.7.20

  A highly regioselective Rh(I)-catalyzed hydrosilylation of enamides is presented. This mild protocol allows access to a wide variety of different arylsilanes with substitution at the beta-position of the enamide and functionalization on the alkyl chain tethered to the silane. This protocol is extended to include a sequential one-pot hydrosilylation. Using diphenylsilane as the appendage point, hydrosilylation of a protected allyl alcohol followed by hydrosilylation of an enamide generates a complex organosilane in one step. This highly convergent strategy to synthesize these functionalized systems now provides a way for the rapid assembly of a diverse collection of silane-based peptidomimetic analogues.

  Silicon alley: SiH and HOR are enantioselectively coupled in the presence of a chiral CuH complex. In this way, the kinetic resolution of racemic mixtures of alcohols is accomplished through asymmetric protection with standard silanes (see scheme; R=aryl or alkyl, Ar=3,5‐xylyl, Np=2‐naphthyl; s=selectivity factor).
