  (1R,5S,6S)-2,2-dimethyl-6-(phenylmethoxymethyl)-5-propan-2-ylcyclohexane-1-carbaldehyde 在 正丁基锂 、 lithium diisopropyl amide 作用下， 反应 4.58h， 生成 [(1S)-2-hydroxy-1,2,2-triphenylethyl] (E,3S)-5-[(1R,5S,6S)-2,2-dimethyl-6-(phenylmethoxymethyl)-5-propan-2-ylcyclohexyl]-3-hydroxypent-4-enoate

  摘要：

  An efficient preparation of novel monocyclic HMG-CoA reductase inhibitors from (R)-(-)-carvone is reported. Utilizing this chiral carbon pool, the C-2 dimethyl seco-mevinic acid 3a was prepared in 17 steps and 5.2 % overall yield. The key chiral intermediate aldehyde 10a was prepared via a short and efficient synthetic sequence (six steps, 27% yield) from (R)-(-)-carvone. The appropriate chirality of the diol acid side chain was secured by employing the chiral acetate synthon ''(S)-HYTRA'' and by performing a stereoselective 1,3-syn reduction on the beta-hydroxy ketone 19. Structural requirements at the C-2 position are rather stringent, and deletion of or addition of an extra methyl group are both unacceptable modifications for this novel class of monocyclic HMG-CoA reductase inhibitors.
