Synthesis of 1,3,5-Trisubstituted Pyrazoles Using Aluminum Chloride

Tang et al. have reported the synthesis of trisubstituted pyrazoles from tosylhydrazones (1) and terminal alkynes (2). According to their results, this reaction is promoted by aluminum chloride and regioselectively proceeds to afford 1,3,5-trisubstituted pyrazoles in high yields. Furthermore, various substituents are applicable to R1 and R2 groups like alkyl, allyl, benzyl and propargyl groups as R1 and aryl groups with electron-donating or -withdrawing groups as R2. It is expected to be used in medicinal chemistry.

Product Highlight

Lewis Pair of Triethylborane and DBU Usable for the Metal-free Copolymerization

A Lewis pair (1) formed from a Lewis acid such as triethylborane and a Lewis base such as 1,8-Diazabicyclo[5.4.0]-7-undecene(DBU) can be used as a metal-free copolymerization catalyst. For instance, a 1-catalyzed regioselective copolymerization of propylene oxide(PO) with carbonyl sulfide(COS) proceeds to give the related polymers with high transparence and high polymerization degree. In this copolymerization, 1 promotes by binding to PO followed by the insertion of COS thereby activating PO, and resultantly gives high tail-to-head content polymers. In this way, 1 is useful for metal-free copolymerizations. Further development of this approach should attract attention.
