Multiple-target drugs may achieve better therapeutic effect via different pathways than single-target ones, especially for complex diseases. Tubulin and DNA are well-characterized molecular targets for anti-cancer drug development. A novel class of diaryl substituted 2H-azirines were designed based on combination of pharmacophores from Combretastatin A-4 (CA-4) and aziridine-type alkylating agents, which are known tubulin polymerization inhibitor and DNA damaging agents, respectively. The antitumor activities of these compounds were evaluated in vitro and 6h showed the most potent activities against four cancer cell lines with IC50 values ranging from 0.16 to 1.40 μM. Further mechanistic studies revealed that 6h worked as a bifunctional agent targeting both tubulin and DNA. In the nude mice xenograft model, 6h significantly inhibited the tumor growth with low toxicity, demonstrating the promising potential for further developing novel cancer therapy with a unique mechanism.

A general, mild, and versatile synthesis of the challenging α-aryl-β-ketosulfoxonium ylides has been developed for the first time, substituting traditional methods starting from diazo compounds. The arylation of easily accessible β-ketosulfoxonium ylides using aryne chemistry allowed the preparation of a large scope of the pro-chiral ylides in very good yields (40 examples; up to 85%). As applications, these ylides were smoothly converted into α-aryl ketones after desulfurization in good yields (up to 98%) as well as in other important derivatives.

The combination of Pd(OAc)2 with 1,3-bis(diphenylphosphino) propane (dppp) in ethylene glycol constitutes a high-performance catalytic system for highly regioselective arylation of a range of electron-rich vinyl ethers by aryl bromides to provide, upon hydrolysis, alkyl aryl ketones and cyclic ketals in good yields with up to 3.75 × 105 TON and 15625 h-1 TOF.

Regioselective hydration of a wide range of internal alkynes has been afforded in high to good yields by using PTSA in EtOH. The scope of the reaction of alkynes has been delineated. Arylaliphatic alkynes and diarylalkynes were regioselectively hydrated in good to excellent yields and short reaction times when the reaction was achieved under microwave irradiation. Moreover, diarylalkynes, arylenynes as well as diaryldiynes bearing a methoxy- or a thiomethyl substituent on the ortho position underwent a regioselective 5-endo-dig-cyclization to give a variety of 2-aryl- and 2-styrylbenzofuran or benzothiphene derivatives. We believe that, this new environmentally metal-free procedure combined to microwave irradiation would be in importance in the search of green laboratory-scale synthesis.
