Abstract

Fukuyama and colleagues have rcently reported the isolation of tricycloillicinone (1) from Illicium tashiroi. 1 Illicinone, 2, also obtained from Illicium tashiroi, might be a biosynthetic precursor of 1. Indeed, in an earlier investigation, photolysis of 2 had been shown to afford 1. 2 Interestingly, compound 2 and its photo product 1 were available from photolysis of 3, 3 the prenylation product of 4. Compound 4 itself is obtained from the pyrolysis of 2 ( ...
