On the Reaction of Triafulvenes with Ynamines
Eichler, Theophil,Pfister, Theodor,Urban, Manfred
, p. 424 - 450 (2007/10/02)
The reaction of triafulvenes 9 - 11 with ynamines 3 leads to 2-aminofulvenes (12, 20, 28, 31), which are characterized by their spectral data, the hydrolysis giving 4-methylene-2-cyclopenten-1-ones (15, 22, 30, 33) and 4-cyclopenten-1,3-diones (14) and by
