Advanced Synthesis & Catalysis
extracted with CH2Cl2, dried over Na2SO4, filtered, and
concentrated under reduced pressure). The pure product
was precipitated from Et2O/npentane, dried in vacuo
overnight, and stored in a glove box to prevent
decomposition.

A Schlenk flask loaded with Na2SO4 (anhydrous, 0.50
mmol, 10 equiv.) was heated with a heat gun and
conditioned with N2 while cooling down to room
temperature. Ligand (12 µmol, 24 mol%) and
[Cu(CH3CN)4]BF4 (10.0 µmol, 20 mol%) were added, and
the flask was evacuated and backfilled with N2. Then,
CH2Cl2 (anhydrous, 2.0 mL, 25 mM w.r.t. nitrene source)
was added and the catalyst solution was stirred at room
temperature for 1 h. Subsequently, diene substrate (75.0
µmol, 1.5 equiv.) was added and the solution was cooled to
0 °C (ice bath) followed by addition of TsNIPh (50.0 µmol,
1.0 equiv.). The reaction was stirred at 0 °C for 1 h. While
still in the cooling bath, the reaction mixture was diluted
with THF (anhydrous, 2.0 mL), and DIPEA (anhydrous,
1.50 mmol, 30 equiv.), Pd2(dba)3 (10.0 µmol, 20 mol%),
and formic acid (1.50 mmol, 30 equiv.) were added. The
ice bath was removed and the reaction mixture was stirred
at room temperature for 2 h. Then, it was passed through a
plug of silica (Pasteur pipette, 5 cm, rinsed with 5 CV
hexanes/EtOAc (50:50)) and concentrated under reduced
pressure. The crude products were purified via automated
normal phase chromatography (silica; CH2Cl2/MeOH; 1
CV: 0%, 12 CV: 0–15%; all fractions containing product—
as determined by UPLC–MS analysis—were collected).
Then, 350 µL internal standard solution (trimethyl trimesic
acid in deacidified CDCl3, 47.7 mM, 16.7 µmol, 0.33
equiv.) was added, the sample was diluted with CDCl3, and
analyzed via NMR spectroscopy (10 s relaxation time).

Site-Selective Retinol Functionalization
A Schlenk flask loaded with Na2SO4 (anhydrous, 1.00
mmol, 10 equiv.) was heated with a hot air gun and
conditioned with N2 while cooling down to room
temperature. Ligand (12 µmol, 12 mol%) and
[Cu(CH3CN)4]BF4 (10.0 µmol, 10 mol%) were added, and
the flask was evacuated and backfilled with N2. Then,
CH2Cl2 (anhydrous, 3.0 mL, 33 mM w.r.t. nitrene source)
was added and the catalyst solution was stirred at room
temperature for 1 h. Subsequently, diene substrate
(100 µmol, 1.0 equiv.) was added and the solution was
cooled to 0 °C (ice bath) followed by addition of TsNIPh
(100 µmol, 1.0 equiv.). The reaction mixture was let warm
up in the cooling bath overnight. Subsequently, it was
passed through a plug of silica (Pasteur pipette, 5 cm,
rinsed with 5 CV hexanes/EtOAc (50:50)). See Figure SI-
21 for UPLC-MS analysis. Then, 700 µL internal standard
solution (trimethyl trimesic acid in deacidified CDCl3, 47.7
mM, 33.3 µmol, 0.33 equiv.) were added and the yield was
determined via NMR spectroscopy (10 s relaxation time).
