Herein we report a highly selective photoredoxC(sp3)−H alkylation/arylation of ethers through the combination of a photo‐organocatalyst (benzaldehyde) and a transition‐metal catalyst (nickel). This method provides a simple and general strategy for the C(sp3)−H alkylation/arylation of ethers. A selective late‐stage modification of (−)‐ambroxide has also been conducted to demonstrate the applicability

Some benzylic-type acetals possessing the 2,8-dioxa-bicyclo [3.2.1]octane ring system are cleaved in a regioselective manner when treated with lithium in ammonia. The results f rom various reductions implicate coordination of lithium as a significant factor involved in reduction mechanisms.
