Dear Fred,

...maybe its too late

I think you can not buy this chemical but you can ask the group in Finland if they
kindly
donate or sell you something.

Or you can ask for the original synthesis.

http://www.helsinki.fi/~orgkm_ww/Hase.html

or other experts (Prof. Herman Adlercreutz).

You can also find a synthesis of  Secoisolariciresinol at
http://www.sciencedirect.com/

Oxidative cyclisation of 3,4-dibenzyltetrahydrofurans using ruthenium

Maybe you already know ChemIDPlus form NIH -  for toxicity you can have a look
(with CAS or name) at
http://chem.sis.nlm.nih.gov/chemidplus/

and you can also search for Secoisolariciresinol in Delphion (world patents and US
patents)

With kind regards
