The photocatalytic construction of C(sp<sup>3</sup>)-rich α-tertiary dialkyl ethers through the reductive α-functionalization of alkyl enol ether substrates with conjugated alkenes in the presence of a Hantzsch ester terminal reductant under blue LED irradiation, is described. Pivoting on oxocarbenium ion generation <i>via</i> an initial TMSCl-facilitated protic activation of the enol ether substrate, subsequent single electron transfer delivers the key nucleophilic α-oxy tertiary radical capable of productively combining with a variety of alkene substrates. The new reductive functionalization strategy was simple to perform, efficient, broad in scope with respect to both alkene acceptor and enol ether donor fragments and delivered a wide range of complex α-tertiary dialkyl ether architectures.
