In this work, we disclose a new catalytic and highly chemoselective cross-Claisen condensation of esters. In the presence of TBSNTf2 as a non-metal Lewis acid, various esters can undergo cross-Claisen condensation to form β-keto esters which are important building blocks. Compared with the traditional Claisen condensation, this process, employing silyl ketene acetals (SKAs) as carbonic nucleophiles to achieve cross-Claisen condensation, requires mild conditions and has good tolerance of functional groups.

The invention provides a novel inhibitor compound shown in a general formula (I). The compound has good kinase inhibition activity and can be used for preventing and/or treating diseases mediated by abnormal expression of TAM family kinase and/or a ligand thereof. The compound can target CSF1R kinase and can be used for preventing and/or treating diseases mediated by abnormal expression of a TAM family kinase receptor and/or a CSF1R kinase receptor and/or ligands thereof.
