Table 2. Substrate Scope of Arylated Selenocysteine^a.

^aSee the Supporting Information for details. Amino acids are shown in a one-letter code. Yields were determined by integration of TICs from LC–MS analyses of the unpurified reaction mixtures (averages of two runs).

^bThe reaction time was 2 h.

^cThe reaction time was 1.5 h.

^d2 mM CuSO₄, 2 mM L2, and 2 mM boronic acid were used.

^e2 mM CuSO₄, 2 mM L2, 2 mM boronic acid, and 90:10 H₂O/DMF for 3 h.
