Abstract:

Mandipropamid is the first mandelamide fungicide on the market. Cyclizing open structures in a given structure represents one of the useful methods in the search for biologically active conformations. A series of novel 3-substituentphenethyl-5-aryloxazolidin-4-ones, the ring-closed analogues of mandipropamid, were obtained from the 2-hydroxy-N-(substitutedphenethyl)-2-arylacetamide and aldehydes by refluxing in benzene or toluene with catalytic amount of p-toluenesulphonic acid. Their structures were identified by means of elemental analysis, IR, 1H NMR and MS spectra. And their structure-activity relationships were discussed.

Key words: Oxazolidinone, Mandelamide, Biological activity
