  Tailoring Buchwald-Type Phosphines with Pyrimidinium Betaines as Versatile Aryl Group Surrogates

  摘要：

  A derivatization of dialkylbiarylphosphines consisting in the formal replacement of their distal aryl group by a pyrimidinium betaine is reported. Two achiral representatives of this new class of Buchwald-type phosphines have been successfully synthesized through two strategies. The first one is based on a last stage introduction of the phosphino moiety, and the second one consists in a modular, one-pot, three-step procedure starting from an o-bromoaryl phosphine. The resulting phosphines have been coordinated onto gold(I) and palladium(II) centers and have been employed as supporting ligands in Pd-catalyzed SuzukiMiyaura cross-coupling of aryl halide substrates.

• Ketone Synthesis by Direct, Orthogonal Chemoselective Hydroacylation of Alkenes with Amides: Use of Alkenes as Surrogates of Alkyl Carbanions

  日期：2019.8

  and direct transformation of carboxamides are two exciting areas that have attracted considerable attention in recent years. We report herein that secondary amides, the least reactive derivatives of carbonyl compounds, upon activated with triflic anhydride, can serve as effective hydroacylating reagents in partner with alkenes to yield ketones at ambient temperature. The method was applied to the one‐step

  烯烃的直接官能化和羧酰胺的直接转化是近年来令人瞩目的两个令人兴奋的领域。我们在此报道，仲酰胺，即羰基化合物的反应性最低的衍生物，在用三氟甲磺酸酐活化后，可以与烯烃一起作为有效的氢酰化试剂，在环境温度下产生酮。该方法已用于外消旋二氢芳基羟色酮的一步合成。在这种方法中，烯烃用作有机金属试剂的替代物，从而可以进行正交的化学选择性反应。许多烯烃（如camp烯和降冰片烯）的现成性允许一步合成酮，而传统方法则需要几个步骤。
• Does formal intramolecular transfer of an acidic deuterium to a site of halogen-lithium exchange show that lithium-halogen exchange is faster than loss of the acidic deuterium? Evidence in favor of an alternative mechanism
  作者：Peter. Beak、Timothy J. Musick、Chin Wen. Chen

  They suggest an alternative in which initial loss of the acidic deuterium is followed by halogen-lithium exchange to give a dilithiated intermediate. Deuterium transfer to the site of halogen-lithium exchange then occurs by reaction of the dilithiated species intermolecularly with unreacted N-deuteriated amide. The halogen-lithium exchange is faster than complete mixing of the reactants and can occur

  酸性氘正式分子内转移到卤素-锂交换位点的反应可以解释为表明最初的卤素-锂交换发生得比酸性氘的损失更快。然而，对 N-deuterio-N-烷基-o、-m-和-p-卤代苯甲酰亚胺的卤素-金属-氘损失之间的竞争的研究与该机制不一致。他们提出了一种替代方案，其中酸性氘的初始损失随后是卤素-锂交换以得到二锂化的中间体。然后通过二锂化物质与未反应的 N-氘化酰胺发生分子间反应，将氘转移到卤素-锂交换位点。卤素-锂交换比反应物的完全混合更快，并且可以在最初形成的去质子化络合物中或在有机锂试剂的瞬时高局部浓度中发生。提供了两种可能性的证据。已经重新研究了文献中卤素-锂交换似乎比酸性氢的转移更快的两个反应，并发现它们可以用相似的序列来解释。

In addition, Tf2O/TTBP combination was used to promote the condensation reactions of 2-(tert-butyldimethylsilyloxy)furan (TBSOF) with both tertiary and secondary amides, the one-pot reductive Bischler–Napieralski-type reaction of tertiary lactams, and Movassaghi and Hill’s modern version of the Bischler–Napieralski reaction. The value of the Tf2O/TTBP-based methodology was further

  The palladium-catalyzed annulation of arynes by substituted o-halobenzamides produces N-substituted phenanthridinones in good yields. This methodology provides this important heterocyclic ring system in a single step by simultaneous C–C and C–N bond formation, under relatively mild reaction conditions, and tolerates a variety of functional groups.

  A novel synthetic pathway to approach 3-(imino)isoindolin-1-ones by the Co-catalyzed cyclization reaction of 2-bromobenzamides with carbodiimides has been developed. This catalytic reaction can tolerate a variety of substituents and provide corresponding products in moderate yields for most cases. According to the literature, the reaction mechanism is proposed through the formation of a five-membered
