A novel synthetic method of HMG-CoA reductase inhibitor NK-104 via a hydroboration-cross coupling sequence
摘要:
The regioselective hydroboration of ethyl (3R, 5S)-3,5-isopropylidenedioxy-6-heptynoate, followed by the cross-coupling reaction with an aryl halide, provides ethyl (3R, 5S, 6E)-7-aryl-3,5-isopropylidenedioxy-6-heptenoate, a precursor of a highly potent HMG-CoA reductase inhibitor NK-104.

The present invention provides compositions of matter, kits and methods for their use in the treatment of MAP kinase-related conditions and/or HMG-CoA reductase-related conditions. In particular, the invention provides compositions for treating inflammatory and/or cardiovascular conditions in an animal subject by inhibiting p38α MAP kinase and/or HMG-CoA reductase, as well as providing formulations and modes of administering such compositions. The invention further provides methods for the rational design of inhibitors of MAP kinase, HMG-CoA reductase, or both for use in the practice of the present invention.

The enantioselectivesynthesis of the C1C9 segment of bryostatins is described. Racemic β-keto ester 2 was subjected to kinetic resolution. Reduction with baker'syeast establishes two of the three chiral centers. Chemical transformation of the terminal acetylene moiety generates aldehyde 5 which is transformed diastereoselectively to the corresponding alcohol 6 via Sakurai reaction.
