The present invention relates to a process for preparing N-(1-alkenyl)carboxamides of the formula I, which comprises reacting a carboxamide of the formula II with an alkyne of the formula III in the presence of a catalyst selected from among carbonyl complexes, halides and oxides of rhenium, manganese, tungsten, molybdenum, chromium and iron.
The present invention relates to a novel class of modified malonate derivatives. The modified malonate compounds can be used to treat cancer. The modified malonate compounds can also inhibit histone deacetylase and are suitable for use in selectively inducing terminal differentiation, and arresting cell growth and/or apoptosis of neoplastic cells, thereby inhibiting proliferation of such cells. Thus, the compounds of the present invention are useful in treating a patient having a tumor characterized by proliferation of neoplastic cells. The compounds of the invention may also be useful in the prevention and treatment of TRX-mediated diseases, such as autoimmune, allergic and inflammatory diseases, and in the prevention and/or treatment of diseases of the central nervous system (CNS), such as neurodegenerative diseases. The present invention further provides pharmaceutical compositions comprising the modified malonate derivatives and safe dosing regimens of these pharmaceutical compositions, which are easy to follow, and which result in a therapeutically effective amount of the modified malonate derivatives in vivo.
