New chiral blocks for introducing the side chain of HMG-CoA reductase inhibitors

A couple of versatile building blocks (8 and 9) of the side chain portion found in many HMG-CoA reductase inhibitors have been prepared. The successful introduction of the side chain to an aromatic ring by 8 or 9 has been demonstrated.

Synthesis of an artificial HMG-CoA reductase inhibitor NK-104 via a hydrosilylation-cross-coupling reaction

The hydrosilylation of t-butyl (3R,5S)-3,5-isopropylidenedioxy-6-heptynoate with ClMe2SiH and a platinum catalyst, t-Bu3P·Pt(CH2 = CHSiMe2)2O, gave an (E)-vinylsilane in high yield with high regioselectivity. A subsequent cross-coupling reaction with an aryl halide afforded t-butyl (3R,5S,6E)-7-aryl-3,5-isopropylidene-dioxy-6-heptenoate. This sequence was applied to the synthesis of a potent HMC-CoA reductase inhibitor, NK-104.
