摘要：
A series of pyrazolylbisindole derivatives have been synthesized by reacting substituted pyrazole aldehydes with substituted indoles using phosphotungstic acid, a Keggin type heteropoly acid as catalyst. The synthesized pyrazolylbisindoles were evaluated for anti-microbial activities. The effect of pyrazolylbisindoles on the mycelial growth of plant pathogenic fungi is revealed. Entries 3c and 3d emerged as the most interesting compounds in this series exhibiting excellent anti-fungal activity. (c) 2006 Elsevier Ltd. All rights reserved.
