Abstract
A sequence consisting of photocatalytic hydrogen atom abstraction (HAT), reductive radical‑polar crossover (RRPCO), and protonation/deuteration for stereochemical editing at benzylic positions is described. A systematic screening of substrates with benzylic C‑H bonds provides trends in reactivity for C‑H activation by silane thiols. A cis/trans isomerization of dihydrobenzofurans proceeding under ...
Abstract
A sequence consisting of photocatalytic hydrogen atom abstraction (HAT), reductive radical‑polar crossover (RRPCO), and protonation/deuteration for stereochemical editing at benzylic positions is described. A systematic screening of substrates with benzylic C‑H bonds provides trends in reactivity for C‑H activation by silane thiols. A cis/trans isomerization of dihydrobenzofurans proceeding under kinetic control in the HAT step is presented and the concept transferred to a deracemization by chiral silane thiols as HAT reagents.
