  achieved by the use of samarium diiodide in catalytic amounts together with mischmetall (an alloy of the light lanthanides) as a coreductant. Plausible catalytic schemes are proposed. In addition, organocerium and -lanthanum reagents have been obtained from samarium diiodide catalysed reactions between organic halides and cerium or lanthanum metal, giving a new route to organolanthanoid compounds.

  日期：1980.5

  A series of 1-(4-biphenylyl)pentyl hydrogen 3-alkylglutarates and 3-hydroxy-3-alkylglutarates was synthesized and assayed for inhibition of rat liver beta-hydroxy-beta-methylglutaryl-CoA reductase. Limited solubility of the monoesters in the enzyme assay system prevented the determination of the I50 values. However, the limited data indicated no significant changes in the activity of the analogs when

  日期：1985.5

  Derivatives of 3-hydroxy-3-methylglutaric acid (HMG), a portion of the substrate for HMG CoA reductase, were prepared and tested for their inhibitory action against rat liver HMG CoA reductase and for their hypocholesterolemic activity. Structure-dependent competitive inhibition was observed. Optimal structures had a free dicarboxylic acid with an alkyl group of 13-16 carbons at position 3. 3-n-Pentadecyl-3-hydroxyglutaric acid (3j) (IC50 = 50 microM) reduced serum cholesterol in the Triton-treated rat and HMG CoA reductase activity in the 20,25-diazacholesterol-treated rat.
• An efficient of Grignard-type procedure for the preparation of gem-diallylated compound

  日期：2007.9

  An efficient and a new procedure for the conversion of various carboxylic acid derivatives into the corresponding gemdiallylated compound under mild reaction condition has been developed. The triallyaluminum mediated Grignard-type addition of carboxylic acid derivative was utilized as a key operation to affect the transformation. The procedure is operationally simple, giving good to excellent product yields for a broad range of substrates. The chemoselectivity and regioselectivity of triallylaluminum were also demonstrated.
