| Abstract: | Trichoderma spp. biosynthesize 6-pentyl-2H-pyran-2-one (6-PP), a natural antifungal pyrone which could be used as biological control agent (BCA). Unfortunately, biotechnical processes are limited by inhibition of biomass at high concentration of 6-PP. We report herein a new easy synthesis of this natural pyrone, using readily available starting materials. This synthesis, compatible with a large production scale, permit to obtain overweight amounts of 6-PP that in biotechnological routes. |
