Synthesis and antifungal activity of analogues of naturally occurring botrydial precursors
摘要:
Analog compounds of the proposed intermediates of the biogenetic pathway to botrydial have been synthesized. These compounds were tested for their potential antifungal activity against the phytopathogen Botrytis cinerea. Our results showed a fungistatic effect of some compounds on mycelium growth. The most significant effect was exerted by 2-alpha-hydroxy-2,3-dihydro-1-epiprobotrydial, which inhibited growth of B. cinerea. Some aspects of structure-activity relationships are discussed.

When epi isn't! The first totalsynthesis of the reportedstructures of 9‐epi‐presilphiperfolan‐1‐ol and presilphiperfolan‐1‐ol has been achieved. Key steps are a catalytic asymmetric alkylation of a novel diene‐containing electrophile followed by a two‐carbon ring contraction and an intramolecular Diels–Alder cycloaddition to form the stereochemically dense tricyclic core. The synthetic work has resulted
