N-Aryl tetrahydroisoquinolines were oxidised to dihydroisoquinolones through the relay catalysis of a binuclear paddle-wheel copper complex and a vitamin B1 analogue with oxygen as oxidant. Mechanistic studies revealed that the copper catalyst oxidises amines to the corresponding iminium salts, which are then oxygenated to lactam products by catalysis of the vitamin B1 analogue.

Acute Painful Diabetic Neuropathy (APDN) is a reversible neuropathy that occurs in patients with diabetes usually after a fast improvement in glycaemic control. The condition is extremely rare in children with Type 1 Diabetes (T1D). We describe a 12-year-old girl T1D who developed APDN shortly after diagnosis of T1D. Neurological examination, nerve conduction studies showed severe asymmetric lower limb sensorimotor neuropathy. She was treated with carbamazepine and benfotiamine (vitamin B1 analogue), and NSAID analgesics and showed complete recovery 9 months after the onset. The treating physicians should recognize and understand this entity in view of the current recommendations for quick achievement of glycaemic targets in T1D, the need to provide relief from severe pain and to lay emphasis on complete recovery.
