  1,3-Dipolar cycloadditions of silicon and tin alkynes and alkenes. Regiospecific synthesis of silyl and stannylpyrazoles and pyrazolines

  摘要：

  Silicon and tin 3-, 3,5-, and 3,4,5-metalated pyrazoles have been synthesized by 1,3-dipolar cycloadditions of silyl-, disilyl-, and silylstannyl acetylenes with N-phenylsydnone or trimethylsilyldiazomethane. On the other hand, 1- and 2-pyrazolines monometalated and dimetalated in different positions of the heterocycle have been prepared by reaction of vinylsilanes and vinylstannanes with the same 1,3-dipolar reagents. Other interesting products resulting from homologation were obtained by cycloaddition of trimethylsilyldiazomethane with beta-silyl enones and esters. Moreover, for the first time a 3-silylpyrazole has been converted into a 3-cyanopyrazole. (c) 2006 Elsevier Ltd. All rights reserved.

  decade has rendered chiral organoiodine(I/III) catalysis a reliable methodology in asymmetric catalysis. However, due to the severely limited numbers of effective organoiodine catalysts, many reactions still give low to modest enantioselectivity. We report herein a solution to this issue through the introduction of a pivotal indanol scaffold to the catalyst design. Our catalyst architecture exhibits

  过去十年的快速发展使手性有机碘（I / III）催化成为不对称催化的可靠方法。然而，由于有效有机碘催化剂的数量非常有限，许多反应仍然给出低至中等的对映选择性。我们在此报告通过在催化剂设计中引入关键的茚满醇骨架来解决该问题的方法。我们的催化剂体系结构具有高度模块化的优势，从而加快了催化剂的优化速度。该催化剂针对2位取代的苯酚在4位进行的具有挑战性和备受追捧的水合脱芳烃反应进行了优化。

  Highly enantioselective catalytic reductive coupling of allyl acetate with acetylenic ketones occurs in a chemoselective manner in the presence of aliphatic or aromatic ketones. This method was used to construct C14-C23 of pladienolide D in half the steps previously required.
