  Flash vacuum pyrolysis of stabilised phosphorus ylides. Part 4. Stepwise construction of terminal 1, 3-diynes, conjugated diacetylenic esters and a triacetylenic ester

  摘要：

  Thirteen examples of stabilised alkynoyl ylides 6 have been prepared and are found, upon flash vacuum pyrolysis (FVP) at 500 degrees C, to undergo extrusion of Ph(3)PO to give the diacetylenic esters 7 in moderate yield. At 750 degrees C the same ylides afforded terminal 1.3-diynes 8 although often in poor yield. For R = 2-MeSC(6)H(4) both 7 and 8 undergo secondary loss of Me(.) and cyclisation to give 2-alkynylbenzothiophene derivatives 9 and 10 in low yield. The first example of an alkadiynoyl ylide 11 has been prepared and is converted by FVP at 500 degrees C into the triacetylenic ester 12.

  日期：——

  A carbene-catalyzed LUMO activation of α,β-unsaturated alkyne esters is reported. This catalytic process allows for effective reactions of alkyne esters with enamides to synthesize functional pyridines via simple protocols. A previously unexplored unsaturated alkyne acyl azolium intermediate is involved in the key step of the reaction.

  heteroarenyne (heteroarene–alkyne) cycloisomerization involving the dearomative transformation of endocyclic aromatic C=C bonds remains unknown. Herein, we communicate a PdH‐catalyzed enantioselective heteroarenyne cycloisomerization reaction of alkyne‐tethered indole substrates (formal 1,5‐ and 1,6‐enynes). Based on this strategy, a variety of structurally diverse chiral spiro and fused indoline derivatives

  广泛开发的经典1，n-炔烃的烯型对映选择性环异构化为手性环状1,4-二烯提供了一种有效的方法。相比之下，催化不对称杂芳烃（杂芳烃-炔烃）的环异构化反应涉及环内芳族C = C键的脱芳烃转化仍然是未知的。在这里，我们交流了炔烃系吲哚底物（正式的1,5-和1,6-烯炔）的PdH催化对映选择性杂芳烃环异构化反应。基于此策略，可以提供中等至优异的收率和优异的对映选择性（高达98％ee）的各种结构多样的手性螺环和稠合的二氢吲哚衍生物，它们带有季立体中心和环外C = C键。N的经典烯型对映选择性1,5-烯炔环异构化还开发了乙烯基丙碘化物，以提供良好至优异ee值的手性2-吡咯烷酮。
