One-Pot Electrooxidative Allylation of Carbamates in the Presence of HBF4 and H2O (Supporting Information)

The one-pot electrooxidative allylation of carbamates was successfully demonstrated in the presence of HBF4 and H2O. Anodic oxidation of carbamates generated the corresponding α-hydroxylated intermediates in the presence of H2O. Without separating the intermediates after electrolysis, reacting them with allyltrimethylsilane in the presence of HBF4 yielded the corresponding α-allylated products in high yields. This method was found to be applicable to several carbamates, except those with an acid-labile Boc protecting group.
