The reaction of 1,3-dicarbonyl compounds with arylidene derivatives of malononitrile and ethyl cyanoacetate leads to the formation of substituted 2-amino-4H-pyrans.In the case of 1,1,1-trifluoro-3-(2-thenoyl)acetone acid cleavage of the Michael adduct occurs, and this leads to 2-aryl-3-(2-thenoyl)-1,1-dicyanopropanes. 1,3-Indanedione reacts by exchange of the methylene components and gives the corresponding 2-arylidene-1,3-indanediones.
