A versatile new synthesis of quinolines and related fused pyridines. Part 9. Synthetic application of the 2-chloroquinoline-3-carbaldehydes
Abstract
The 2-chloro-groups of the title compounds have been replaced by H, I, OH, SR, Li, CO2H, CHO, Ph, piperidine, and N3(giving a tetrazole). The aldehyde group has also been converted into oxime, hydrazone, and acrylic acid derivatives. From these and related derivatives a variety of fused quinolines have been made including thieno-, pyridazino-, tropono-, pyrano-, thiopyrano-, and furo-quinolines.
