, p. 1695 - 1698 (2017)
The reaction of aryl acetylide anions with phenyl isocyanate and subsequent addition of a protonating agent such as ethanol affords good yields of 3-aminomaleimides, formed by the cyclization of one molecule of alkyne with two isocyanates. When the reaction is quenched with water instead, cyclopentadienone imines are formed as the major products.
Synthesis and Reaction Behaviour of 2-Aryl-3-chloro-maleimides
Augustin, M.,Faust, J.,Koehler, M.
, p. 293 - 300 (2007/10/02)
2-Aryl-3-chloro-maleimides 2 are prepared by the chlorination of aryl-maleicanhydrides and aminolysis of the resulting 1-aryl-2-chloro-maleicanhydrides 1.The imide 2a is reacted with N-, S-, O- and C-nucleophiles and inorganic salts to give 2,3-disubstitu
