Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Synlett called A one-pot method for the synthesis of naphthyridines via modified Friedlander reaction, Author is Zhichkin, Pavel; Cillo Beer, Catherine M.; Rennells, W. Martin; Fairfax, David J., which mentions a compound: 1569-17-1, SMILESS is CC1=C2C=CC=NC2=NC=C1, Molecular C9H8N2, Formula: C9H8N2.
A one-pot method for the preparation of 1,8-naphthyridine derivatives is reported. The method involves the dimetalation of an appropriate N-2-pyridylpivalamide or tert-butylcarbamate followed by reaction with a β-dimethylamino- or β-alkoxyacrolein derivative This method is also applicable to 1,6-naphthyridines.
Compounds in my other articles are similar to this one(4-Methyl-1,8-naphthyridine)Formula: C9H8N2, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
