, p. 96762 - 96767 (2016/10/24)
An environmentally benign, mild, cost-effective and gram-scalable copper-catalyzed method for the N-(hetero)arylation of zwitterionic natural and unnatural amino acids using 2-isobutyrylcyclohexanone as a β-diketone ligand and aryl bromides as coupling partners in water for 50 min at 90 °C under microwave irradiation is reported. Electronically and sterically diverse aryl coupling partners were inserted efficiently, including challenging heteroaryl electrophilic partners in high yields without affecting the enantiopurity of the product.

Keten. Part 17. Addition Reactions of Ketens with N-Phenyl Nitrones

The N-phenyl nitrones (1a), (4b), and (15) react with ketens in two totally different ways.Triphenylnitrone (4b) forms oxidolones (6) whereas (1a) and (15) form oxazolidinones (2) and (17).The differences appear to be caused by steric interactions in (1a) and (15) which distort the nitrone function and prevent the N-phenyl group adopting the conformation necessary for the oxindole-forming pathway.
