  • An Acyl-Claisen Approach to Tetrasubstituted Tetrahydrofuran Lignans: Synthesis of Fragransin A2, Talaumidin, and Lignan Analogues
    作者:David Barker、Claire Rye
    DOI:10.1055/s-0029-1218363
    日期:2009.12
    A simple and stereocontrolled synthesis of racemic 2,3,4,5-tetrasubstituted tetrahydrofurans was achieved from acyl-Claisen derived syn-disubstituted amides.

  • Bioinspired total synthesis of tetrahydrofuran lignans by tandem nucleophilic addition/redox isomerization/oxidative coupling and cycloetherification reactions as key steps
    作者:Pratap R. Jagtap、Ivana Císařová、Ullrich Jahn
    DOI:10.1039/c7ob02848b
    日期:——
    A very short three-step approach to trans,trans,trans-2,5-diaryl-3,4-dimethyltetrahydrofuran lignans is reported. The carbon skeleton is assembled in a single step based on an unprecedented tandem reaction consisting of 1,2-addition of aryllithium reagents to α,β-unsaturated aldehydes, ruthenium-catalyzed redox isomerization of the resulting alkoxides to enolates and their dimerization triggered by

    日期:2007.2
    A new ring closure to tetrasubstituted tetrahydrofurans from the intramolecular attack of an OMOM ether onto a benzylic mesylate proceeds through a quinonoid intermediate or by direct S N 2 displacement. The synthesis of diastereomeric biologically active natural lignans is described utilizing this general methodology.

    作者:Hosam Choi、Jongyeol Han、Joohee Choi、Kiyoun Lee

    日期:——
    In this study, the divergent syntheses of (-)-chicanine, (+)-fragransin A2, (+)-galbelgin, (+)-talaumidin, and (+)-galbacin are detailed. In this approach, an early-stage modified Kowalski one-carbon homologation reaction is utilized to construct the central γ-butyrolactone framework with the two necessary β,γ-vicinal stereogenic centers. The two common chiral γ-butyrolactone intermediates were designed

  • Synthesis of All Stereoisomers of 3,3′-Dimethoxy-7,7′-epoxylignane-4,4′-diol and Their Plant Growth Inhibitory Activity
    作者:Hisashi Nishiwaki、Kumiko Nakayama、Yoshihiro Shuto、Satoshi Yamauchi
    DOI:10.1021/jf4046396
    日期:2014.1.22
    All stereoisomers of 3,3'-dimethoxy-7,7'-epoxylignane-4,4'-diol were synthesized to examine the effect of stereochemistry on their plant growth inhibitory activity using lettuce and Italian ryegrass. The effect of structural modifications such as dehydroxylation, methoxylation and hydroxylation at the 9- and 9'-positions of the lignans on the activity was also studied. Most of the epoxylignanes showed higher plant growth inhibitory potency against ryegrass than against lettuce, and the inhibitory activity varied depending on the configurations of each position of the tetrahydrofuran ring (7-, 7'-, 8-, and 8'-positions of the epoxylignanes). Among the 9,9'-position-modified derivatives, the dehydroxy derivatives showed the highest potency. These results suggested that the plant growth inhibitory activity should be influenced by the structure of the epoxylignanes.
