Convenient synthesis of 2-Amino-4H-chromenes from photochemically generated o-quinone methides and malononitrile

2-Amino-4H-chromenes were synthesized in moderate to good yields by the reaction of o-quinone methides photochemically generated from o-(dimethylaminomethyl)phenols with malononitrile. This method was applicable to the synthesis of fluorinated chromenes that were difficult to obtain by other methods. In addition, o-(hydroxymethyl)phenols could be used for the reaction in the presence of tertiary amine bases.

Synthesis, structure-activity relationship (SAR) studies on some 4-aryl-4H-chromenes and relationship between lipophilicity and antitumor activity

Some 4-aryl-4H-chromenes 3a-h, 5a-g, 7a-g and 9a-g were obtained by reaction of 3-substituted phenol 1,4,6 and 8 with α-cyanocinnamonitrile derivatives 2. We explored the structure activity relationship (SAR) of 4-aryl-4H-chromenes with modification at th
