Chandler, Christopher J. published the artcileThe synthesis of macrocyclic polyether-diesters incorporating 1,10-phenanthrolino and 1,8-naphthyridino subunits, COA of Formula: C10H10N2, the publication is Journal of Heterocyclic Chemistry (1982), 19(5), 1017-19, database is CAplus.
Macrocycles I (n = 2-4) and II (n = 3, 4) were prepared by treating the resp. acid chlorides with HO(CH2CH2O)nH. 2,7-Dimethylnaphthylridine was prepared in 60% yield from III by thermal rearrangement to ketone IV, followed by chlorination with POCl3 and hydrogenolysis. III was obtained by treating 6-methyl-2-pyridinamine with MeCOCH2CO2Et.
Journal of Heterocyclic Chemistry published new progress about 14903-78-7. 14903-78-7 belongs to naphthyridine, auxiliary class 6.6_Aromatics,Naphthyridines, name is 2,7-Dimethyl-1,8-naphthyridine, and the molecular formula is C10H10N2, COA of Formula: C10H10N2.
