Quinazoline studies. Part XII. Action of acid and alkali on quinazoline

Journal of the Chemical Society C: Organic, 1968
Quinazoline was converted into 2-aminobenzaldehyde and its anhydro-polymers (the trimer, the tetramer, and the monoformyl-tetramer) by the action of hot dilute acid or alkali. The substance of high-molecular weight formed from quinazoline below pH 1·5 was found to be a polymer of the 3,4-adduct of the latter with 2-aminobenzaldehyde.

5-Substituted quinazoline antifolates

European Journal of Cancer (1965), 1980
Abstract Two new 5 -substituted- 2 -amino- 4 -hydroxy-quinazoline antifolates are described. The presence of the 5 -substituent reduced the inhibitory effect upon thymidylate synthetase. In contrast, the 2,4 -diaminoquinazoline series, the same 5 -substituents improved the inhibition.

Pyrimidines and quinazolines

1975
Publisher Summary This chapter covers the literature for the period from the latter part of 1994 to the early part of 1998. This period has seen the continued use of pyrimidine drugs—such as AZT and ddC in the treatment of viral diseases and the development of new analogues of these compounds, for example, 3TC (3’-thiocytosine).

Quinoline, quinazoline, and acridone alkaloids

Natural Product Reports, 1984
The most interesting new alkaloids are the acridones that contain tropone rings, which have been isolated from Citrus species. Emphasis this year is again on synthesis, with highlights including the first use of copper acetylides in the synthesis of furoquinolones, the synthesis of the (1,l -dimethylallyl)quinolinone buchapine, and developments in the ...
