  FeCl2介导的菲咯啉配体加速碘代烷的亲核氯化

  摘要：

  Alkyl halides have been considered not only important building blocks but also useful intermediates in synthetic methods of nucleophilic substitution, metal-halogen exchange, and cross-coupling reactions. As the practical synthesis of various alkyl halides, the halogen exchange is one of the fundamental and efficient reactions, which is mainly used for preparing alkyl bromides or iodides. Finkelstein-type reactions(1) have been well studied for the conversion of alkyl chlorides to the corresponding bromides or iodides and alkyl bromides to iodides, which reaction is an equilibrium shifted by taking advantage of the different solubility of the resulting sodium salt in acetone. However, the reverse processes, the replacement of iodide by bromide or chloride, or of bromide by chloride, were not simple.

  Synthesis of α-Amino Ketones from Terminal Alkynes via Rhodium-Catalyzed Denitrogenative Hydration of N-Sulfonyl-1,2,3-triazoles

  摘要：

  N-Sulfonyl-1,2,3-triazoles react with water in the presence of a rhodium catalyst to produce alpha-amino ketones in high yield. An intermediary alpha-imino rhodium(II) carbenoid undergoes insertion into the O-H bond of water. This transformation formally achieves 1,2-aminohydroxylation of terminal alkynes in a regioselective fashion when combined with the copper(I)-catalyzed 1,3-dipolar cycloaddition with N-sulfonyl azides.

  The enantioselective synthesis of P-stereogenic chiral organophosphines under organocatalysis is a challenging research field, and reports that use this approach are rare. Herein, we have developed the enantioselective synthesis of P-stereogenic chiral oxazaphospholidines by using a bicyclic thiazole as the organocatalyst in the P–N and P–O bond-forming reaction. The P-chiral products were prepared

  在有机催化下对映选择性合成 P-立体手性有机膦是一个具有挑战性的研究领域，使用这种方法的报道很少。在此，我们通过使用双环噻唑作为 P-N 和 P-O 键形成反应中的有机催化剂，开发了对映选择性合成 P-立体手性 oxazaphosphollides。P-手性产物以高产率制备，对映选择性适中。该过程中使用的碱对反应的对映选择性有显着影响，在某些情况下会导致 P-手性中心的相反构型。

  Herein we describe the PhI(OAc)2-mediated 1,1- and 1,2-difunctionalization of alkenes with N-tosyl amino alcohols to form oxazolidine and morpholine derivatives. This transformation was realized under mild reaction conditions and allows application to various substrates furnishing the multi-substituted oxazolidines and morpholines with yields up to 98%. A deuterium-labeling experiment was carried out
