Developing continuous syntheses of lead compounds to support in vivo studies and preclinical evaluation remains an underdeveloped area. We report a telescoped continuousflow synthesis of an alkynylnaphthyridine lead compound for the treatment of FLT3 mutations in acute myeloid leukemia. Different strategies were used to develop the route, including Design of Experiments (DoE), high-throughput experimentation
Two ligands with different geometries have been prepared to synthesize new silverâethynide complexes bearing pyridyl and carboxylate groups. Reactions of 5-ethynylnicotinic acid (H222L1) and 5-ethynylpicolinic acid (H222L2) with silver nitrate afforded [Ag2(L1)·AgNO3]n (1) and [Ag12(L2)6·12AgNO3]·5H2O}n (2), respectively. Crystallographic studies revealed that in 1, the L1 ligands connect linear silver chains to form a 2D layer through silver-ethynide interactions and Ag-carboxylate coordination bonds, and subsequently the layers are further linked through AgâN(pyridyl) coordination bonds to generate a 3D network; however in 2, the L2 ligand interacts with Ag8 units through AgâN, AgâO coordination bonds, silverâethynide interactions and ÏâÏ stacking directly to assemble a 3D network. In the solid state, both complexes are luminescent at room temperature, assigned as the intraligand nâÏ* and ÏâÏ* transitions.

Inspired by diversity-oriented synthesis, we have developed a series of DNA-compatible transformations utilizing on-DNA vinyl azide as a synthon to forge divergent N-heterocyclic scaffolds. Polysubstituted imidazoles and isoquinolines were efficiently obtained with moderate-to-excellent conversions. Besides, the “one-pot” strategy to prepare in-house on-DNA vinyl azides afforded synthons readily. Results
受多样性导向合成的启发,我们开发了一系列 DNA 相容的转化方法,利用 DNA 上的乙烯基叠氮化物作为合成子来制造不同的 N-杂环支架。多取代的咪唑和异喹啉以中等至优异的转化率有效地获得。此外,在内部制备 DNA 乙烯基叠氮化物的“一锅法”策略很容易提供合成子。底物范围探索和酶促连接的结果进一步证明了这些 N-杂环合成在 DNA 编码化学文库构建中的可行性。
