Abstract

3-Benzoylguaiazulene (I) and methyl guaiazulene-3-carboxylate (XI) were heated at 250– 260° C. From 3-benzoylguaiazulene we obtained, besides S-guaiazulene (II), three new azulenoids, which were established to be 2-benzoylguaiazulene (III), 1-benzoyl-7-isopropyl- 3, 4-dimethylazulene (IVa) and 2-benzylguaiazulene (V). On the other hand, the products yielded from methyl guaiazulene-3-carboxylate, together with S-guaiazulene, were ...
