starting materials. For these reasons, deaminative functionalization of amines has emerged as an important area of research. Recent advances in C-N activation transform simple α-1° and α-2° amines into alkylating reagents via Katritzky pyridinium salts. We report a complementary method that activates sterically encumbered α-3° primary amines through visiblelight photoredox catalysis. By condensing α-3°
methyl ester (4) was prepared from the following sequence of reactions: esterification of trans-4-hydroxy-l-proline (2), Boc protection, and fluorination by DAST. Reaction of 4 with lithiated oxadiazole provided oxadiazolyl ketone 7. Deprotection of the Boc group of 7 and subsequent coupling with bromoacetyl bromide gave bromide 9. Coupling reaction of 9 with excess oxazolidine 16 provided coupled product

N‐chlorosuccinimide (NCS) was employed as the oxidant in the synthesis of aniline derivatives using the title transformation (see scheme). Functionalization was well tolerated on both the amine and Grignard reagent. An androgen receptor agonist and several analogues were synthesized to demonstrate the utility of this method.
