Synthesis of Chiral Tetrahydrofurans and Pyrrolidines by Visible‐Light‐Mediated Deoxygenation
The synthesis of chiral tetrahydrofurans and pyrrolidines starting from 1,2‐diols or β‐amino alcohols, respectively, by visible‐light‐mediated deoxygenation is described. Easily accessible monoallylated/propargylated substrates were activated either as inexpensive ethyl oxalates or as recyclable 3,5...

| Sumario: | The synthesis of chiral tetrahydrofurans and pyrrolidines starting from 1,2‐diols or β‐amino alcohols, respectively, by visible‐light‐mediated deoxygenation is described. Easily accessible monoallylated/propargylated substrates were activated either as inexpensive ethyl oxalates or as recyclable 3,5‐bis(trifluoromethyl)benzoates to generate alkyl radicals suitable for 5‐exo‐trig/5‐exo‐dig cyclizations under visible‐light irradiation. |
