- 中文摘要:
Pyrano[4,3-d]pyrimidine derivative 3 was prepared by reaction of chlorocarbonyl isocyanate 1 with enaminonitrile 2.
Compound 3 reacted with nitrogen nucleophiles 4a-f to afford 2-substituted pyrido[4,3d]pyrimidine 5-8, pyrimido[i]1,5a-diaza-9-oxafluorene 9 and pyrimido[i]5a-aza-9-thiafluorene 10 derivatives. Also, compound 3 reacted with active methylene compounds 4j to yield pyrimidine derivatives 14-16 which on reaction with EtONa 4k afforded 1,5,7-triaza-10-oxaphenanthrene derivatives 17-19. - 英文摘要: --
