  A One-Pot Condensation of Pyrones and Enals. Synthesis of 1H,7H-5a,6,8,9-Tetrahydro-1-oxopyrano[4,3-b][1]benzopyrans

  摘要：

  Condensation of various 6-substituted 4-hydroxypyrones 1 with 1-cyclohexenecarboxaldehydes in the presence of L-proline in ethyl acetate gave high yields of substituted 1H,7H-5a,6,8,9-tetrahydro-1-oxopyrano[4,3-b][1]benzopyrans. The reaction presumably occurs via the 1,2-addition of the pyrone with the aldehyde followed by dehydration and then cyclization through a 6 Pi electrocyclic process. A remarkable asymmetric induction was obtained from a stereogenic center (C4) of the cyclohexenecarboxaldehyde [such as (S)-perillaldehyde] to provide only the C5a,7-trans tricyclic pyrone products. On the other hand, condensation of S-(formyloxy)- or 3-hydroxy-2-methyl-1-cyclohexene-carboxaldehydes with pyrones 1 gave mixtures of C5a,6-cis and -trans products. Several of the tricyclic pyrones strongly inhibit acetylcholinesterase activity, DNA synthesis, and tumor cell growth in vitro.

  (EN) This invention provides cancer-active tricyclic and tetracyclic oxypyrones and a method of synthesizing these compounds. Preferred compounds have aryl groups at the 3-position of the oxypyrone ring. The tricyclic oxypyrone synthetic method is a simple condensation reaction of pyrones with cyclohexenecarboxaldehydes, providing high yields and using few steps. The tetracyclic oxypyrone synthetic method is a simple condensation reaction of carvones with pyrones.(FR) La présente invention concerne des oxypyrones tricycliques et tétracycliques actifs contre le cancer, ainsi qu'une méthode de synthétisation de ces composés. De préférence, les composés comprennent des groupes aryle à la position 3 du noyau d'oxypyrone. La méthode de synthétisation d'oxypyrone tricyclique consiste en une simple réaction de condensation de pyrones avec des cyclohexènecarboxaldéhydes, produisant des rendements élevés et nécessitant peu d'opérations. La méthode de synthétisation d'oxypyrone tétracyclique consiste en une simple réaction de condensation de carvones avec des pyrones.
