The present disclosure provides certain tricyclic compounds that are histone methyltransferases G9a and/or GLP inhibitors and are therefore useful for the treatment of diseases treatable by inhibition of G9a and/or GLP such as cancers and hemoglobinopathies (e.g., beta-thalassemia and sickle cell disease). Also provided are pharmaceutical compositions containing such compounds and processes for preparing such compounds.

Bromoamination of unfunctionalized olefins was realized under mild conditions using copper(II) bromide (CuBr2) as both reaction promoter and bromine source. The reactions could be carried out under open air at ambient temperature, and both N‐alkylated and N‐tosylated substrates could be converted to the corresponding N‐heterocyclic compounds in high regioselectivity and good isolated yields. A variety

studied. Preliminary results indicated that both steric and electronic factors are crucial for this Lewisacid-promotedreaction. ZnI2 gave the most promising results and the reactivity could be further increased upon addition of a suitable ligand. Up to 95% isolated yields were obtained when the reactions were carried out in 1,4-dioxane in the presence of 10 mol % of ZnI2 and 8-hydroxyquinoline.
phenyselenenyl bromide to afford ring closure reaction products deriving by the intramolecular capture of the seleniranium intermediates by the oxygen atom. Owing to the relative positions of the oxygen atom and of the carbon-carbon double bond in the nitrones employed, six-memberedcyclic iminium salts were thus formed. These have ben directly treated with nucleophilic reagents and afforded 1,2-oxazine derivatives

bifunctional catalyst promoted the hydroamination of various primary and secondary aminoalkenes at mild temperatures (50–110 °C) without side reactions such as oxidative amination. Cyclization of secondary aminoalkenes containing ester, cyano, bromo, and hydroxy groups occurred with maintenance of these functional groups, while the reactions of aminoalkenes bearing allylic substituents proceeded with a perfect
