A very unusual high yield of rearranged products (via methyl migration) has been obtained in the Fischer indole cyclization of the 3-(2,5-dimethyl phenylhydrazone) of 2,3-piperidine dione (6b). When a less activated aromatic ring is present in the phenylhydrazone 6, such a behaviour is not observed and cyclization occurs essentially without rearrangement.

The invention is directed to β-carboline sulphonylurea derivatives as EP4 receptor antagonists useful for the treatment of EP4 mediated diseases or conditions, such as acute and chronic pain, inflammation, osteoarthritis, and rheumatoid arthritis. Pharmaceutical compositions and methods of use are also included.
A novel series of quinazolino-beta-carbolinone derivatives was synthesized and evaluated for their in vitro and in vivo anticancer activity. Many compounds have shown good in vitro activity in the range 1-8 muM concentration. Three of the compounds were further tested in nude mice bearing HT-29 colon cancer xenografts.
