Mosallanejad, Arash published the artcileApplication of Tsunoda reagent to the convenient synthesis of drug-like pyrazoles, Quality Control of 622-40-2, the publication is Tetrahedron Letters (2018), 59(18), 1708-1710, database is CAplus.
The versatility of the under-utilized (cyanomethylene)tributylphosphorane (CMBP, Tsunoda reagent) was demonstrated on two occasions in a drug discovery context. Firstly, the high reactivity of the phosphorane allowed the alkylation of a weakly acidic pyrazole when standard Mitsunobu conditions were unsuccessful. Secondly, the clean reaction profile generally obtained using CMBP allowed the direct use of the crude mixture in a subsequent Suzuki cross coupling. This reagent was utilized when isolation of the Mitsunobu reaction product (e.g. containing a boronate) was not desirable.
