Application of Secondary Amines in the Synthesis of Some New Spiro Heterocyclic Compounds
摘要:
1-Anilinocycloalkanecarbonitriles 1a-c were prepared and reacted with active methylene reagents to give compounds 5a-c through 10a-c and reacted with different other reagents such as benzaldehyde, ethyl aminoacetate, ethyl mercaptoacetate, or hydrazine carbothioamide, which afforded the desired spiro heterocycles compounds 11a-c through 14a-c.
