Synthesis, X-ray structure determination and germination studies on some smoke-derived karrikins

Popis výsledku v původním jazyce

The discovery of the karrikin class of plant growth regulators (PGRs) is a milestone accomplishment in plant biochemistry and physiology, with significant potential in agriculture and horticulture. These compounds have in common a fused furano-pyran ringsystem featuring various permutations of methyl substitution. Chief amongst these compounds is karrikinolide (KAR(1)), identified as the key germination stimulant present in plant-derived smoke, which together with five other closely-related structures(KAR(2)-KAR(6)) make up the karrikin class of PGRs. By contrast, the germination inhibitor 3,4,5-trimethyl-2(5H)-furanone has also been identified in plant-derived smoke. Various synthetic endeavours have been undertaken for structure-activity relationship study purposes as well as to probe the molecular mechanics of these compounds. In this study, syntheses of KAR(1), KAR(3) and S-KAR(1) were carried out and their structures verified by X-ray crystallography. Effects on germination were
