    • 1Ha NMR spectra in the Supporting Information for this experiment). The stepwise decrease in the peak area at δ=5.43a ppm indicates that the α-hydrogen of 1a is gradually deuterated under the acidic conditions. This experiment thus provides evidence for the transformation of 1 into intermediate A as described in Schemea 5.
