A Mild and Efficient Procedure for Ring-Opening Reactions of Piperidine and Pyrrolidine Derivatives by Single Electron Transfer Photooxidation

Various N-arylamino-1-pyrrolidines and N-arylamino-1-piperidines are selectively converted into the corresponding acyclic aminoaldehydes or amino-dialkylacetals under mild photooxidation conditions.
