Three-component synthesis of 2-imino-1,4-benzoxazines
摘要:
A series of 2-imino-1,4-benzoxazines (8a-e) were prepared by the one-pot, three-component, condensation of salicylaldehyde (4), various ortho-aminophenols (5), and 2,6-dimethylphenylisonitrile (6). The structures of four of the crystalline benzoxazine derivatives (8b-e) were unambiguously established by X-ray analysis. (C) 2009 Elsevier Ltd. All rights reserved.
