  • Title: Synthesis of multiply 13C-labeled furofuran lignans using 13C-labeled cinnamyl alcohols as building blocks.
    Author: Haajanen K, Botting NP.
    Journal: Steroids; 2006 Mar; 71(3):231-9. PubMed ID: 16360720.
    Abstract:
    Plant lignans are currently being widely studied for their potential benefits for human health as their consumption has been correlated with lower risks for developing chronic diseases, such as breast cancer and coronary heart disease. However, studies of some classes of lignans, in particular the furofurans, are hampered by the lack of suitable standards to allow accurate analysis. Herein, we report the syntheses of two racemic (13)C-labeled furofuran lignans [7,8,9-(13)C(3)]medioresinol and [7,8,9-(13)C(3)]sesamin as internal standards for LC-MS analysis. The labeled furofuran lignans were constructed from triply labeled cinnamyl alcohols, using a radical cyclization method.
