Abstract
Instead of the expected 2,4-dihydroxy-3-quinolyl-3-butanol, the product of its cyclization in the form of the angular isomer-2-methyl-5-hydroxypyrano[3,2-c]quinoline — is obtained in the reduction of 2,4-dihydroxy-3-quinolyl-3-butanone with aluminum, isopropoxide. Some transformations of 2,4-dihydroxy-3-(3-chlorocrotyl)quinoline were investigated.
