  摘要：

  本文涉及通过采用新型的NBS溴化途径合成1,16-二羟基四亚苯基（DHTP）（2）。（+/-）-DHTP 2成功解析为其旋光对映体，并转化为（+/-）-1,16-双（二苯基膦基）四亚苯基（BPTP）（26），其铂络合物BPTP-PtCl（2）（ 27）。作为氢键供体，使外消旋和旋光的DHTP 2与4,4'-联吡啶组装形成优质的单晶。这些晶体的X射线衍射研究表明，（+/-）-2和4,4'-联吡啶之间的氢键配合物的晶体堆积不同于由（S）-2和4,4'形成的混合物-联吡啶。发现在（+/-）-2和4,4'-联吡啶的组装物中形成了具有交替手性的无限之字形链，而（S）-2和4,4' -联吡啶未能显示出相同的组装模式。（+/-）-2与4,4'-联吡啶形成交替的锯齿形链的原因很可能是由于这种超分子组装体的固有稳定性所致。还研究了在铂（II）方向上2和旋光性BINAP之间的手性识别。（1）H和（31）P N

  Facile organocatalytic domino oxidation of diols to lactones by in situ-generated TetMe-IBX

  摘要：

  The domino oxidation of diols to lactones is an important transformation, and catalytic protocols that allow this conversion smoothly are scarce. Capitalizing on the established reactivity of tetramethyl-IBX (TetMe-IBX) and its in situ generation in the presence of a co-oxidant, such as oxone, we have shown that a variety of diols can be converted to the corresponding lactones in respectable yields by employing the precursor of TetMe-IBX, namely, tetramethyl-o-iodobenzoic acid (TetMe-IA), as a catalyst in 5 mol % in the presence of 2 equiv of oxone.

  Enantioselective catalytic methods allowing the addition of both a nucleophile and an electrophile onto diazo compounds give a fast access into important building blocks. Herein, we report the highly enantioselective oxyalkynylation of diazo compounds using ethynylbenziodoxol-(on)e reagents and a simple copper bisoxazoline catalyst. The obtained α-benzoyloxy propargylic esters are useful building blocks
