  Metal-Free C–H Amination for Indole Synthesis

  摘要：

  An effective metal-free C-H amination of N-Ts-2-alkenylanilines by using DDQ as an oxidant has been developed to afford a diverse range of substituted indoles. This protocol is operationally simple and robust, obviates the need of expensive transition-metal catalysts, and offers a broad substrate scope. A mechanism involving a radical cation generated by SET and a migratorial process via a phenonium ion intermediate is proposed.

  日期：2013.6.3

  CH activation: The ruthenium‐catalyzed direct sp2 CH amidation of arenes by using sulfonyl azides as the amino source is presented (see scheme). A wide range of substrates were readily amidated including arenes bearing weakly coordinating groups. Synthetic utility of the thus obtained products was demonstrated in the preparation of biologically active heterocycles.

  An efficient Ru(II)-catalyzed intermolecular amidation of weakly coordinating ketones with sulfonyl azides via C-H bond activation is described. The reaction proceeds with high functional group tolerance, providing a novel approach to practical ketone-directed intermolecular C-N bond formation in the absence of an additional oxidant.

• One-Pot Phosphine-Catalyzed Syntheses of Quinolines
  作者：San Khong、Ohyun Kwon

  DOI：10.1021/jo3015825

  日期：2012.9.21

  In this study we developed an efficient one-pot procedure for the preparation of 3-substituted and 3,4-disubstituted quinolines from stable starting materials (activated acetylenes reacting with o-tosylamidobenzaldehydes and o-tosylamidophenones, respectively) under mild conditions. The reaction appears to operate under a general base catalysis mechanism, instigated by the beta-phosphonium enoate alpha-vinyl anion generated in situ through nucleophilic addition of PPh3 to the activated alkyne. Michael addition of the deprotonated tosylamides to the activated alkynes and subsequent rapid aldol cyclization led to the formation of labile N-tosyldihydroquinoline intermediates. Driven by aromatization, detosylation of the dihydroquinoline intermediates occurred readily in the presence of dilute aqueous HCl to give the final quinoline products.
