Abstract
Synthesis of some quinazoline derivatives was carried out with their plant protection capabilities in mind. The syntheses of 17 substances from this group (among them 6 new ones) have been completed. Different substituents have been introduced, first in position 4, then in position 2 and 4 of quinazoline, then two substituents to both rings (e.g. hydroxyl, chlorine, piperidyl, hydrazine, ethanolamine). The above‐mentioned compounds were tested in the first stage from the point of view of their fungicidal, insecticidal and herbicidal activity. One compound (4‐chloroquinazoline) was taken to the second stage of investigations because of its fungicidal activity. It has not qualified, however for further investigations.Keywords
