  Enantioselective Total Synthesis of (+)-6-epi-Mevinolin and Its Analogs. Efficient Construction of the Hexahydronaphthalene Moiety by High Pressure-Promoted Intramolecular Diels−Alder Reaction of (R,2Z,8E,10E)-1-[(tert-Butyldimethylsilyl)oxy]-6-methyl-2,8,10-dodecatrien-4-one

  摘要：

  3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, (+)-6-epi-mevinolin (2a) and (+)-6-epi-4a,5-dihydromevinolin (2b), were prepared by combining two nonracemic units, phosphonate 3 and decalin 4, which were prepared from enantiopure 3-substituted pentanedioic acid monoesters 5a and 5b, respectively. Each acid was synthesized from cyclic anhydrides 7a and 7b by diastereoselective ring opening by means of (S)-benzyl mandelate as a common chiral auxiliary. The construction of decalin moiety 4 was accomplished by asymmetric intramolecular Diels-Alder (IMDA) reaction of nonracemic trienone 6 bearing a methyl group as a chiral controller. The IMDA diastereoselectivity of trienone 6 is discussed in terms of the configuration of(E)- and (Z)-dienophiles which are activated by an endogenous carbonyl group. The IMDA reaction of(R)-(Z)-6 under high pressure is highly selective and gives cis-decalins exclusively with preferential formation of 4 over 16. The inhibitory activity of (+)-6-epi-mevinolin (2a) and several analogs against HMG-CoA reductase was compared with mevinolin (1b). (+)-6-epi-Mevinolin (2a) was shown to be half as potent as mevinolin (1b) while (+)-6-epi-4a,5-dihydromevinolin (2b) was as potent as mevinolin.

  (EN) The new strain $i(Aspergillus terreus) CCM 8236 was obtained by means of classic mutagenesis procedures. The process of aerobic fermentation of lovastatin by the strain of $i(Aspergillus terreus) CCM 8236 in the form of acid in a submersion culture in a laboratory scale is described. The inoculum was prepared in a broth having low pH value. The mixture of glucose and lactose (at the ratio of 1:22) at the high concentration and Pharmamedia is used as the carbon and nitrogen source, respectively. The strain produced more than 2000 mg/l of lovastatin during 170 hours in the above-mentioned broth.(FR) On a produit la nouvelle souche $i(Aspergillus terreus) CCM 8236 au moyen de procédures de mutagénèse classiques. On décrit le procédé de fermentation aérobie de lovastine à l'aide de la souche d'$i(Aspergillus terreus) CCM 8236 sous forme d'acide dans une culture en submersion réalisée dans une bascule de laboratoire. L'inoculat a été préparé dans un bouillon de culture ayant un faible pH. Le mélange de glucose et de lactose (suivant le rapport de 1:22) à une concentration élevée et le Pharmamédia est utilisé respectivement en tant que source de carbone et d'azote. La souche a produit plus de 2000 mg par litre de lovastine pendant 170 heures dans le bouillon de culture mentionné ci-dessus.
