Copies of assigned papers and questions for discussion are distributed in class. In some cases, a modified version of the paper containing markups, comments, and additional questions will be emailed to you – please examine this version on your computer. The following links provide access to the original paper (no markups) and my questions for discussion.

I am having difficulty finding the NMR spectra for compound 3. The synthesis lists the spectral data, but when you scroll down to the “selected spectra” there is not one for 3.

if you go to the experimental section where they write up the syntheses of each compound they list spectral data. I found the spectra data for compound 3 there.

Ian – I don’t see “selected spectra” Are you looking at the Supporting Info file (48 pages)? I had no problem finding data for compound 3 in the Supporting Info, page S-5.

I found the spectral data, chem shift and splitting patterns and what-not, however the instructions say to look at the NMR spectra itself, that is what I cannot find.

I think I understand. Just use the data listed on page S-5. The Supporting Info doesn’t contain physical copies of any of the spectra for compound 3.

Okay, cool. Thanks
