Conversion of 2-aryl-4-dichloromethylen-5(4H)oxazolones to 5-acylamino-substituted pyrimidine bases
摘要:
Available polycentral unsaturated azlactones with 4-dichloromethylene group by successive treating with benzamidine and then with morpholine or its analogs were converted to substituted 5-acylamino-4-hydroxypyrimidines containing the residues of the corresponding nitrogen bases in the position 6. The structure of these cyclization products is consistent with the scheme of their preparation and has been confirmed also by H-1 NMR spectroscopy and XRD analysis.
