Zhang, Li published the artcileRegioselective synthesis of polysubstituted N2-alkyl/aryl-1,2,3-triazoles via 4-bromo-5-iodo-1,2,3-triazole, Category: pyridine-derivatives, the publication is Synlett (2012), 23(7), 1052-1056, database is CAplus.
The regioselective N(2)-substitution of 4-bromo-5-iodo-1,2,3-triazole with alkyl/aryl halides in the presence of K2CO3 in DMF produced the desired 2-substituted 4-bromo-5-iodo-1,2,3-triazoles as major products in good to excellent regioselectivity. Subsequent chemoselective Suzuki-Miyaura cross-coupling of N(2)-substituted 4-bromo-5-iodo-1,2,3-triazoles provided polysubstituted 1,2,3-triazoles efficiently.
Synlett published new progress about 197958-29-5. 197958-29-5 belongs to pyridine-derivatives, auxiliary class Pyridine,Boronic acid and ester, name is 2-Pyridinylboronic acid, and the molecular formula is C13H10N2S, Category: pyridine-derivatives.
