The present invention relates to 3,4-substituted piperidinyl - based renin inhibitor compounds bearing at 4-position lsoqumolone and having the Formula (I) : The invention further relates to pharmaceutical compositions containing said compounds, as well as their use in treating cardiovascular events and renal insufficiency.
of a methoxy group on an aromatic ring allows this group to be used as a traceless activating and directing group for aromatic functionalization reactions. Although several catalytic methods for the reductive cleavage of anisole derivatives have been reported, all are applicable only to π-extended aryl ethers, such as naphthyl and biphenyl ethers, while monocyclic aryl ethers cannot be reduced.

A methodology is reported for the preparation of various aromatic-functionalized vinylethers using a Wittig approach. The subsequent hydrogenation of the vinylether products to their saturated analogs is also performed and is streamlined by employing continuous-flow processing.

The first iron-catalyzed formal cross coupling of homobenzylic methyl ethers with alkyl Grignardreagents is realized. The reaction is proposed to proceed through a sequence of dehydroalkoxylation to form the vinyl-intermediate, followed by Fe-catalyzed selective carbometalation to form a benzylic Grignardreagent.
