3-Hydroxy-N-methylwelwitindolinone C isonitrile (3), 3-hydroxy-N-methylwelwitindolinone C isothiocyanate (4), and the novel cyclic ether N-methylwelwitindolinone D isonitrile (6) are three new alkaloids from two terrestrial Fischerella spp. belonging to the Stigonemataceae. Photooxidation of N-methylwelwitindolinone C isonitrile (1) leads to isonitriles 3 and 6. Isonitrile 3 is readily hydrated to 3-hydroxy-N-methylwelwitindolinone C formamide (5), an artifact produced during the isolation… CONTINUE READING
