The present invention relates to compounds of formula (I)
wherein R1, R2 and R3 are as defined in the description,
to their pharmaceutical compositions and use thereof for the treatment of cancer expressing oncogenic ALK protein, particularly anaplastic large cell lymphoma (ALCL), diffuse large B cell lymphoma (DLBCL), inflammatory myofibroblastic tumours (IMT) and non-small cell lung cancer (NSCLC).
A high‐yielding, copper‐catalyzed dearomatization reaction of indole from 2‐methylindole‐derived oxime acetates was realized, providing access to structurally novel spiro[indoline‐3,2′‐pyrrolidine] derivatives in 67–98% yields. When the C‐2 position of the indole was not substituted, azacarbazole derivatives were obtained in moderate yields. This transformation provides an efficient approach to access

Acyl oximes derived from a variety of indolylalkanones underwent a ring closure sequence during FVP to afford 9H-pyrido[2,3-b]indoles. Unlike UV light promoted reactions of oxime esters, the mechanism is almost certainly not mediated by iminyl radicals but probably involves tautomerism, elimination of acetic acid, and a final electrocyclic ring closure.

A new synthesis of α-carbolines was developed starting from the easily accessible 3-substituted indol-2(3H)-one derivatives 2 and enamines 3. The intermediates 4 afforded the α-carbolines 5 and 6 by thermal cyclization with ammonium acetate in glacial acetic acid by way of pyridine ring formation.
Compounds comprising a metal complex having novel ligands are provided. In particular, the compound is an iridium complex comprising novel aza DBX ligands. The compounds may be used in organic light emitting devices, particularly as emitting dopants, providing improved efficiency, low operating voltage, and long lifetime.
