Synthesis and spectroscopic characteristation of a combinatoiral library based on the fungal natural product 3-chloro-4-hydroxyphenylacetamide

Abstract

Parallel solution-phase chemistry has yielded a series of secondary amide analogues of the fungal natural product 3-chloro-4-hydroxyphenylacetamide. 3-Chloro-4-hydroxyphenylacetic acid was coupled to a variety of primary amines using 1-ethyl-3-(3-dimethylamino- propyl)-carbodiimide hydrochloride. The desired products were obtained in good yield and high purity following rapid silica purification. All analogues were spectroscopically characterised using NMR, UV, IR and MS data. One compound displayed moderate cytotoxicity against the human melanoma and prostate cell lines, MM96L and DU145. Copyright 頲007 John Wiley & Sons, Ltd.
