DOTTADs—readily made novel metal ligands with multivariant functionality and chirality
摘要:
A variety of novel ligands have been generated by Vilsmeier formylation of Hantzsch pyridines. These compounds which we call DOTTADs contain two aldehyde, imine or amine functions flanking a central pyridine nitrogen and can be homochiral or crown derivatives. The synthesis and manipulation of these systems is discussed. (C) 2000 Elsevier Science Ltd. Ail rights reserved.
