  Synthesis and inhibitory activity of 4-alkynyl and 4-alkenylquinazolines: Identification of new scaffolds for potent EGFR tyrosine kinase inhibitors

  摘要：

  The present study identified several 4-alkynyl and 4-alkenylquinazolines that serve as novel and potent EGFR tyrosine kinase inhibitors. The IC50 values of these compounds are in the nanomolar range. In addition, the 4-(4-phenylbut-1-yl/en-yl)quinazolines provided scaffolds for potent enzyme inhibition. Chiral discrimination was observed to occur in one of the 4-alkynylquinazoline derivatives with the (R)-isomer being more than 150 times as potent as the (S)-isomer. (c) 2007 Elsevier Ltd.

  A general synthesis of 2-formyl-3-arylpyrroles

  摘要：

  2-Formyl-3-iodo-1 -tosylpyrrole 2 has been prepared in four steps from cinnamaldehyde. It was coupled with a wide variety of arylboronic acids to give the corresponding biaryl compounds in high yields. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.

  Suzuki cross-coupling reactions of 3-pyrroleboronic acid derivatives with haloaromatics and the reverse process i.e., the coupling of 3-iodo(bromo)pyrroles with arylboronic acids have been investigated as a potential key step in the synthesis of (–)-rhazinilam and analogues. It was found that 3-iodo-2-formyl-1-tosylpyrroles efficiently coupled with a variety of arylboronic acids in the presence of PdCl₂(dppf) as catalyst. This catalytic system is compatible with a broad spectrum of arylboronic acids — electron-rich, electron-poor, hindered, heterocyclic — which easily coupled with the pyrrole substrate.Key words: 2-substituted-3-arylpyrroles, biaryls, coupling reactions, arylboronic acids, palladium coupling, catalysis.
