The present invention relates to certain compounds (e.g., imidazopyrazine, imidazopyridine, imidazopyridazine and imidazpyrimidine compounds) that act as inhibitors of the MAP kinase interacting kinases MNK2a, MNK2b, MNK1a, and MNK1b. The present invention further relates to pharmaceutical compositions comprising these compounds, and to the use of the compounds for the preparation of a medicament for the prophylaxis and treatment of diseases (e.g., proliferative diseases (e.g., cancer), inflammatory diseases, Alzheimer's disease), as well as methods of treating these diseases.

A convenient general method for the synthesis of a new heterocycle, spiro[azetidine-2,4′(1′H)-iso-quinoline-1′,3′,4(2′H)-trione] is described. The key intermediate 2 was prepared by direct halogenation of position-4 of acid 3 with thionyl chloride, and subsequent treatment of the generated 4-Cl, 4-acetyl chloride 11 with a THF/NH3 solution at low temperature.

A highly diastereo‐ and enantioselective Mannich reaction of isatin‐derived N‐Boc imines with homophthalic anhydrides is disclosed for the first time, which allows the direct synthesis of a wide range of oxindole‐derived α‐aryl‐β‐amino acids with two adjacent carbon stereogenic centers in a highly stereoselective fashion (up to >95:5 dr & >99% ee). The resulted Mannich adducts can be easily converted
