This study presents an enantioselective oxidative cyclization ofN-allyl carboxamides via a chiral triazole-substituted iodoarene catalyst. The method allows the synthesis of highly enantioenriched oxazolines and oxazines, with yields of up to 94% and enantioselectivities of up to 98% ee. Quaternary stereocenters can be constructed and, besidesN-allyl amides, the corresponding thioamides and imideamides are well tolerated as substrates, giving rise to a plethora of chiral 5-memberedN-heterocycles. By applying a multitude of further functionalizations, we finally demonstrate the high value of the observed chiral heterocycles as strategic intermediates for the synthesis of other enantioenriched target structures.

Constrained analogues of procaine were synthesized, and their inhibiting activity against DNMT1 was tested. Among them, the most potent compound, derivative 3b, was also able to induce a recognizable demethylation of chromosomal satellite repeats in HL60 human myeloid leukemia cells and thus represents a lead compound for the development of a novel class of non-nucleoside DNMT1 inhibitors.
