Krieger, Jean-Philippe published the artcileRhodium(III)-Catalyzed C-H Activation/Heterocyclization as a Macrocyclization Strategy. Synthesis of Macrocyclic Pyridones, Synthetic Route of 1293990-73-4, the publication is Organic Letters (2017), 19(10), 2706-2709, database is CAplus and MEDLINE.
Structurally diverse macrocyclic pyridones can be efficiently synthesized by a rhodium(III)-catalyzed C-H activation/heterocyclization of ¦Ø-alkynyl ¦Á-substituted acrylic hydroxamates. The use of a O-pivaloyl hydroxamate as directing group was crucial to achieve efficient catalyst turnover in a redox-neutral process.
