10b was produced through reaction of 9 with acetophenone. Reaction of 1 with benzylidinemalononitrile afforded 11. New methods for preparation of 15 and 16 are described. The reaction of 8 with malononitrile, thio-semicarbazide, phenyl hydrazine and acetophenone afforded compounds 18-21. The reaction of 21 with malononitrile gave 22. Compounds 23-26 were produced upon reaction of 10a with malononitrile
