Screening study for potential lead compounds for natural product‐based fungicides: I. Synthesis and <i>in vitro</i> evaluation of coumarins against <i>Botrytis cinerea</i>

Abstract

An efficient, one-pot synthesis of angular and linear dihydropyranocoumarins, along with C-6 and C-8 prenylated coumarins is reported. These compounds, together with single- and furanocoumarins, were tested for their potential antifungal activity against the phytopathogen Botrytis cinerea Pers ex Fr. The results show that furanocoumarins may be able to control the fungus B cinerea.
