摘要

Abstract The 't-amino effect'of amino-nitroso compounds was documented by preparing the (dialkylamino)-nitroso pyrimidines 4–18, and cyclising them under thermal conditions in high yields to the purine derivatives 19–32. The reactivity of the amino-nitroso-pyrimidines, particularly of 17 derived from diethyl iminodiacetate, and of 19, derived from 1- phenylimidazolidine, correlates with the stability of the intermediate azomethine ylide. ...
