Abstract
Способ получения замещенных пиридинкарбоновых кислот путем озонолиза хинолинов формулы (I), которые в положении 2, и/или 3, и/или 4 замещены остатком R, а также в положении 6 и/или 7 - остатком R, причем Rи Rозначают H или C-C-алкильную группу и Rи Rозначают инертную в условиях реакции группу и, по меньшей мере, один из остатков Rи Rне является H, в кислом водном растворе при температуре от -5 до +40°C подвергают взаимодействию с озоном, полученный таким образом раствор выдерживают 0,5-15 ч при температуре от 0 до 100°C для разложения образовавшихся перекисей при подаче кислорода или воздуха, и соответствующую замещенную пиридинкарбоновую кислоту формулы (II), в которой Rимеет вышеуказанное значение и Rи Rозначают OH или C-C-алкильную группу, причем, по меньшей мере, один из радикалов Rи Rне является OH, выделяют из реакционной смеси.Отчет о международном поиске был опубликован 2000.03.16.
