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.
3-Hydroxyisothiazole exists as the lactim in nonpolar solvents, the lactam form predominating in aqueoussolution. Acylation, although extremely rapid in nonpolar solvents, depends on the relative rates of reaction of the two tautomers rather than on their relative proportions. The size of the acyl group, and the steric requirements of the catalyst, are shown to be the critical factors in determining
