  Cyclizations of phenylethyl-substituted pyridinecarboxaldehydes

  摘要：

  Several phenylethyl-substituted pyridinecarboxaldehydes were prepared from 2-bromo-3-pyridinecarboxaldehyde and these substances are found to undergo cyclization reactions in acidic media. In the absence of added nucleophile, acid-promoted cyclization and oxidation (MnO2) provide an efficient route to 10,11-dihydro-5H-benzo[4,5]cyclohepta[1,2-b]pyridin-5-ones. Arene nucleophiles may also be added to the acidic mixture to provide good yields of triarylmethane products. Mechanisms are proposed involving dicationic superelectrophilic intermediates.

• Rapid access to benzo-annelated heterocycles, naphthalenes, and polysubstituted benzenes through a novel benzannulation reaction
  作者：Inga Cikotiene、Rita Buksnaitiene、Rokas Sazinas

  DOI：10.1016/j.tet.2010.11.073

  日期：2011.1

  mercaptoacetate triggered benzannulation reaction is described. The precursors are heterocyclic, aromatic or acyclic compounds bearing a carbonyl group at ortho position to an internal alkyne. The methodology does not require transition-metal catalysts and moreover it is general for the preparation of wide range of benzo-annelated heterocycles, naphthalenes and benzenes.

  An efficient and convenient method for the synthesis of indol-3-yl benzo[b][1,6]- and benzo[c][2,7]naphthyridines via copper(II) triflate-catalyzed heteroannulation is reported. This method gives new analogues of indole containing benzonaphthyridines from easily accessible starting materials. This reaction proceeds under mild conditions.

  provides pyrano[4,3-b]quinolines 4a−f, via formation of cyclic iodonium intermediate Q; however, using alcohols as a solvent as well as nucleophile, o-alkynyl esters 5a−y were obtained selectively in good to excellent yields via formation of hypoiodide intermediate R. Subsequently, o-alkynyl esters were converted in to pyranoquinolinones 6a−i and isocoumarin 6j by electrophilic iodocyclization. This

  Published as part of the Special Topic Recent Advances in Amide Bond Formation Abstract A post-Passerini condensation transformation can be employed in the synthesis of three types of amides: α-hydroxy, α-oxy, and α-oxo amides. K2CO3 efficiently promotes the solvolysis of α-acetoxy amides to form α-hydroxy amides in methanol. 2-Acetoxy-2-(2-alkynyl­quinolin-3-yl)acetamides in basic methanol are cyclized
