The title compound, C~22~H~25~N~3~O~3~, also known as fumitremorgine C, was isolated from the ethyl acetate extract of Penicillium __sp__. To a first approximation, the molecule is flat with the exception of the –C(H)=CMe~2~ side arm, which is perpendicular to the remaining atoms. Molecules associat
