• Synergistic Effect of Palladium and Copper Catalysts: Catalytic Cyclizative Dimerization of ortho-(1-Alkynyl)benzamides Leading to Axially Chiral 1,3-Butadienes

  Two is better than one: In the presence of Pd(OAc)2 and Cu(OAc)2, o‐(1‐alkynyl)benzamides 1 were converted into bis‐iminobenzoisofurans with an axially chiral 1,3‐diene 2 unit. The coexistence of both Pd and Cu catalysts was found to be essential for both the cyclizative dimerization process and for the observed unusual cyclization mode.

  两种优于一种：在Pd（OAc）2和Cu（OAc）2存在下，邻-（1-炔基）苯甲酰胺1被转化为具有轴向手性1,3-二烯2单元的双亚氨基苯并异呋喃。发现钯和铜催化剂的共存对于环化二聚过程和观察到的异常环化模式都是必不可少的。
• Triaryl-Like MONO-, BIS-, and TRISKITPHOS Phosphines: Synthesis, Solution NMR Studies, and a Comparison in Gold-Catalyzed Carbon–Heteroatom Bond Forming 5-<i>exo</i>-dig and 6-<i>endo</i>-dig Cyclizations

  A homologous series of triaryl-like KITPHOS-type monophosphines containing one, two, or three bulky 12-phenyl-9,10-dihydro-9,10-ethenoanthracene (KITPHOS) units have been developed, and the influence of increasing steric bulk on their efficacy as ligands in gold(I)-catalyzed carbon-heteroatom bond-forming cyclizations has been investigated. Detailed solution NMR studies on Ph-TRISKITPHOS, its oxide, and the corresponding gold(I) chloride adduct identified a conformational exchange process involving a concerted librational motion of the individual anthracene-derived organic substituents about their P-C bonds. The cessation of this motion at reduced temperatures lowers the molecular symmetry such that the two C6H4 rings in each of the KITPHOS units become inequivalent; a lower energy process involving restricted rotation of the biaryl-like phenyl ring has also been identified. Electrophilic gold(I) complexes of these triaryl-like KITPHOS monophosphines catalyze the 5-exo-dig cycloisomerization of propargyl amides to afford the corresponding methylene oxazolines, which were used in a subsequent tandem carbonyl-ene reaction to afford functionalized 2 -substituted oxazolines. A comparative survey revealed that catalyst efficiency for cycloisomerization decreases in the order MONOKITPHOS = BISKITPHOS > PPh3 > TRISKITPHOS. The optimum system also catalyzes the selective 6-endo-dig cyclization of 2-alkynylbenzyl alcohols, 2-alkynylbenzoic acid, and 2-phenylethynyl benzamides; gratifyingly, in several cases the yields obtained are markedly higher and/or reaction times significantly shorter than those previously reported for related gold catalysts. Moreover, these are the first examples of gold(I)-catalyzed 6-endo-dig cycloisomerizations involving 2-phenylethynyl benzamides and, reassuringly, the optimum gold(I)/MONOKITPHOS systems either rivaled or outperformed existing silver or palladium based catalysts. The steric parameters of this homologous series of phosphines have been quantified and compared with selected triarylphosphines using a combination of Solid -G calculations, to determine the percentage of the metal coordination sphere shielded by the phosphine (the G parameter), and Salerno molecular buried volume calculations (SambVca) to determine the percent buried volume (%V-bur); the corresponding Tolman cone angles have also been determined from correlations.
