Hawad, Hacan published the artcileDeprotonation of pyridine carboxamides using lithium magnesates bases, Related Products of chlorides-buliding-blocks, the publication is Tetrahedron (2008), 64(14), 3236-3245, database is CAplus.
Regioselective deprotonation of N-methyl- and tert-butylpyridine carboxamides using lithium magnesates bases was achieved at room temperature avoiding nucleophilic addition on the pyridine mol. and auto-condensation of the arylmetal intermediates on the amide group was described. The hydrogen-magnesium exchange was evidenced using 1H NMR spectroscopy at room temperature and the reactivity of the lithium 2-, 3- and 4-carboxamidopyridinylmagnesiates complexes towards electrophiles and in cross-coupling reactions was studied.
Tetrahedron published new progress about 6313-54-8. 6313-54-8 belongs to chlorides-buliding-blocks, auxiliary class Pyridine,Chloride,Carboxylic acid, name is 2-Chloroisonicotinic acid, and the molecular formula is C6H4ClNO2, Related Products of chlorides-buliding-blocks.
