7-dihydroxy-N-nor-ketone (VI) in several steps; this product (II) was identical with the alkaloid. Another minor alkaloid from the same plant, fumariline, was also prepared from compound (VI). The imino-group was protected by forming an imidazolidinone ring with methyl isocyanate. Methylenation of the dihydroxy-system followed by treatment with lithium aluminium hydride to remove the imidazolidinone ring gave 1,2,3
