Haematopodin

Haematopodin is the more stable breakdown product of Haematopodin B.[1] Both compounds are found in the mushroom Mycena haematopus, although haematopodin only occurs in trace amounts in fresh fruit bodies. Similar pigments (with the 1,3,4,5-tetrahydropyrrolo[4,3,2-de]quinoline structure), known as batzellins and damirones, have been found in sea sponges.[1] A chemical synthesis for haematopodin was reported in 1996. Key steps in the synthesis involved the addition of 3-[(2,4-dimethoxybenzyl)amino]-1-propanol to the indolo-6,7-quinone and cyclization of the resulting adduct with trifluoroacetic acid.[2]
