摘要

A number of derivatives of isoxazolo [5, 4-d] pyrimidine have been prepared as potential purine antagonists. Condensation of hydroxylamine with methylethoxymethylenemalononitrile, ethylethoxymethylenemalono-nitrile, and phenylmethoxymethylenemalononitrile gave a series of 3-substituted 4-cyano-5- aminoisoxazoles which, upon reaction with ethyl orthoformate-acetic anhydride, followed ...
