Quinazolines. Part X. The fragmentation of quinazolines under electron impact

Journal of the Chemical Society B: Physical Organic, 1967
Quinazoline, under electron impact, fragments by the consecutive loss of two molecules of HCN to give a benzyne radical ion. Fragmentation of substituted quinazolines also occurs by this pathway as well as by others normally associated with the breakdown of the substituent.

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).
