  N-Alkylation of tosylhydrazones via a metal-free reductive coupling procedure

  摘要：

  A simple metal-free route for the N-alkylation of tosylhydrazones is described via the NaOMe-promoted reductive coupling of tosylhydrazones under mild conditions. A wide variety of N-alkylated tosylhydrazones were obtained in moderate to good yields. (C) 2012 Elsevier Ltd. All rights reserved.

  -quaternary centers via regioseletive C-C bond activation has been described. Through cyclopropanation of bench-stable enaminones with in situ generated diazo reagents from N-tosylhydrazones, followed by selective C-C bond cleavage of the cyclopropane ring affords the 1, 4-ketoaldehyde derivatives in good to excellent yields. This method works with broad substrate scope and high regioseletivity.

  A novel palladium(0)‐catalyzed intermolecular coupling reaction of 2‐gem‐dibromovinylanilines and N‐tosylhydrazones was reported to construct 2‐(1‐phenylvinyl)‐indoles efficiently. The indole bearing 1, 1‐disubstituted alkenes were obtained in one step with short reaction time, in high yields and broad substrate scope. The formed indole derivates could be easily transformed into much more valuable
