n the Supporting Information of this paper, the H NMR
spectrum for synthesized colletoic acid was found to have
I
been edited to remove solvents and impurities. The above
compound was resynthesized, and the new spectrum is
provided in the revised Supporting Information submitted
with this correction. The spectrum editing did not affect any of
the conclusions of the published paper. The yield was found to
be correct.
