An efficient microwave-assisted solvent-free synthesis of pyrido-fused ring systems applying the tert-amino effect
摘要:
Significant improvements in the synthesis of pyrido-fused heterocycles were observed when performing the reaction under solvent-free conditions, applying the tert-amino effect as the key ring closure methodology. An unexpected cyclization of ortho-(1'-azacycloalkyl)benzaldehydes has been studied in water and on solid support. (c) 2005 Elsevier Ltd. All rights reserved.
