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, Chemische Berichte called Vicarious nucleophilic substitution of hydrogen, bisannulation and competitive reactions of α-haloalkyl carbanions with bicyclic azaaromatic compounds, Author is Makosza, Mieczyslaw; Golinski, Jerzy; Ostrowski, Stanislaw; Rykowski, Andrzej; Sahasrabudhe, Arvind B., which mentions a compound: 1569-17-1, SMILESS is CC1=C2C=CC=NC2=NC=C1, Molecular C9H8N2, Application In Synthesis of 4-Methyl-1,8-naphthyridine.
Carbanions of RR1CHSO2R2 (I; R = Cl, R1 = H, Me, R2 = NMe2, Ph, CMe3, morpholino, tolyl; R = Br, R1 = H, R2 = tolyl) react with bicyclic heteroaromatic compounds (quinoxalines, naphthyridines, and 5-azaquinoxalines) according to 2 general pathways: vicarious nucleophilic substitution (VNS) of hydrogen and/or bisannulation. In some cases other competitive reactions are observed Factors governing the direction of these reactions are discussed in terms of the charge distribution in the anionic σ adducts and the reaction conditions. For example reaction of quinoxaline and quinoxaline N-oxide with I (R = Cl, R1 = H, R2 = Ph) gave bisazirinoquinoxaline II and VNS product III resp.
After consulting a lot of data, we found that this compound(1569-17-1)Application In Synthesis of 4-Methyl-1,8-naphthyridine can be used in many types of reactions. And in most cases, this compound has more advantages.
