A metal-free chemoselective oxidation of 4-methylquinolines into the corresponding aldehydes using phenyliodine(III) diacetate as the oxidant. This mild oxidation method provides an attractive alternative for synthesis of N-heteroaromatic aldehydes.
with anilines to afford β-amino ketones which are converted into substituted quinolines in a one-pot fashion. The exclusive preference for N-alkylation over N-allylation makes this approach unique when compared to those reported in literature. Detailed mechanistic investigations reveal that the conjugate addition pathway was the predominant one over the allylic amination pathway. The notable aspects of
