The dithiophenes and trithiophenes reviewed in this article are part of a large group of biogenetically related molecules found in plants of the family Compo sitae (Asteraceae). They include compounds having a variable number of unsaturations, particularly double bonds and triple bonds, which occur singly or in combinations. The first report of a naturally occurring trithiophene, ex-terthienyl in the flowers of Tagetes erecta, appeared in 1947 (270); the first naturally occurring dithiophene was isolated from Bidens radiata and described in 1961 (142). The book Naturally Occurring Acetylenes,...
