The aldehyde group is one of the most versatile intermediates in synthetic chemistry, and the introduction of an aldehyde group into heteroarenes is important for the transformation of molecular structure. Herein, we achieved the direct formylation of benzothiazo/les and isoquinolines. The reaction features a novel iron-catalyzed Minisci-type oxidative coupling process using commercially available 1,3-dioxolane as a formylated reagent followed by acetal hydrolysis without a separation process. The reaction can be performed under exceedingly mild reaction conditions and exhibits broad functional group tolerance.

A series of benz-fused five-membered heterocyclic compounds were designed and synthesized as novel tubulin inhibitors targeting the colchicine binding site. Among them, compound 4d displayed the highest antiproliferative activity against four cancer cell lines with an IC50 value of 4.9?μM in B16-F10 cells. Compound 4d effectively inhibited tubulin polymerization in vitro (IC50 of 13.1?μM). Further, 4d induced cell cycle arrest in G2/M phase. Finally, 4d inhibited the migration of cancer cells in a dose-dependent manner. In summary, these results suggest that compound 4d represents a new class of tubulin inhibitors deserving further investigation.
