    • (7′ R, syn)-streptorubin B (retention time ? 10 minutes) could be detected in the samples of synthetic (7′ RS) and (7′ R)-streptorubin B (see the Supporting Information). It was not detectable in the sample of streptorubin B isolated from S. coelicolor because it constitutes only ∼0.5% of the mixture [the anti/syn ratio is ∼88:7 and only ∼5% of (7′ R, anti)-streptorubin B is present in the natural product].

    • 4 would also reduce the ester in 13 to the corresponding alkoxide, which would be expected to displace iodide in an intramolecular reaction to form the corresponding tetrahydrofuran. Thus, a different synthetic approach for the stereospecific deuterium-labeling of 2-undecylpyrrole at C-4′ would be required.
