Synthesis of pyrazole-containing azacrown ethers by intramolecular nitrilimine cycloadditions
摘要:
Intramolecular cycloadditions of suitably functionalised nitrilimines have been exploited to prepare a number of crown azaethers having a medium or large ring annulated to pyrazole unit(s). (C) 1997 Elsevier Science Ltd.
