Isonitrile acids from cultures of the fungus Trichoderma hamatum(Bon.) Bain. aggr., X-ray structure
Abstract
Two acids have been isolated from cultures of the above fungus as the corresponding methyl esters; one is shown by X-ray crystallographic analysis to be methyl 3-(3-isocyano-6-oxabicyclo[3.1.0]hex-2-en-5-yl) acrylate (1), the other is probably methyl 3-(3-isocyanocyclopent-2-enylidine) propionate (2).
