, p. 583 - 592 (2007/10/02)
A new route to the cycloalkeno-pyridines 2 and cycloalkeno-thiopyrans 5 by the reaction of malononitrile with enamines of cyclic β-ketocarbothionic acid anilides is presented.The elucidation of the structure of compounds obtained is based on MS spectral d
Reaction of Methylene Active Nitriles and Cyanamide with Acylated Enamines
Gewald, K.,Schaefer, H.,Bellmann, P.
, p. 933 - 941 (2007/10/02)
The addition products from enamines onto isocyanates and isothiocyanates, i.e. substituted β-aminoacrylo amides 1 and thioamides 2, react with malononitrile to yield the 6-amino-1-aryl-5-cyano-pyridin-2-ones 3 and -thiones 4 among them 5,6,7,8-tetrahydroi
