A series of novel analogs of pyrrole alkaloid were designed and synthesized by a facile method and their structures were characterized by H-1 NMR, C-13 NMR and high-resolution mass spectrometry (HRMS). The structure of compound 2a was identified by 2D NMR including heteronuclear multiple-quantum coherence (HMQC), heteronuclear multiple-bond correlation (HMBC) and H-H correlation spectrometry (H-H COSY) spectra. Their antifungal activities against five fungi were evaluated, and the results indicated that some of the title compounds showed moderate fungicidal activities in vitro against Alternaria solani, Cercospora arachidicola, Fusarium omysporum, Gibberella zeae and Physalospora piricola at the dosage of 50 mu g mL(-1). Compound 2a and 3a exhibited good activities against P. piricola at low dosage. (C) 2011 Elsevier Masson SAS. All rights reserved.
