THE BIOSYNTHESIS OF THE PHENETHYLISOQUINOLINE ALKALOID, COLCHICINE, FROM CINNAMALDEHYDE AND DIHYDROCINNAMALDEHYDE
Herbert, Richard B.,Knagg, Eric
, p. 1099 - 1102 (1986)
The important phenethylisoquinoline alkaloid, colchicine (10) is shown to derive from cinnamic acid (5) via cinnamaldehyde (6) and dihydrocinnamaldehyde (7); dihydrocinnamic acid (4) may be used by a minor pathway.
