Synthesis of novel chiral macrolides and their antifungal activity
摘要:
Nineteen chiral macrocyclic diamide-diester ligands were synthesized using a three step reaction. The synthesis utilized the condensation of dicarbonyl dichlorides with chiral 2-aminoethanol derivatives. The reaction was catalyzed in a dual catalyst system. Some of the compounds were found to display antifungal activity. (C) 2003 Elsevier Science Ltd. All rights reserved.

A series of new hetero-macrocyclic diamide-ester compounds (4a — 4z, 6a — 6b) were synthesized using 4-(dimethylamino)pyridine as catalyst and characterization by infrared spectra, nuclear magnetic resonance spectra, mass spectra and elemental analyses. The structures of 4e and meso 4b were determined by X-ray crystallography. The association constants of the compounds with various metal ions were
