Platinum-Catalyzed Desaturation of Lactams, Ketones, and Lactones

The development of a general platinum-catalyzed desaturation of N-protected lactams, ketones, and lactones to their conjugated α,β-unsaturated counterparts is reported. The reaction operates under mildly acidic conditions at room temperature or 50 °C. It is scalable and tolerates a wide range of functional groups. The complementary reactivity to the palladium-catalyzed desaturation is demonstrated in the efficient conversion of iodide, bromide, and sulfur-containing substrates.

Photochemistry of Some Azaphenanthrene N-Oxides

1- and 4-Azaphenanthrene N-oxides undergo solvent-dependent photoisomerization, yielding naphtho-1,3-oxazepines in aprotic solvents and benzoquinolin-1(2H)-ones in water.No ring enlargement but only isomerization to the corresponding lactam is observed to take place in the case of 9-azaphenanthrene N-oxide.Measurements of the quantum yield of two photoprocesses (lactam formation and ring enlargement) confirm the difference between the photochemical behaviour of 9-azaphenanthrene N-oxide and that of the other two N-oxides examined
