“…Recent interest in methods of conjugated diyne synthesis has resulted in several syntheses being reported (Scheme ). For example, Ziegler et al used the phosphacumulene ylide derived from 107 to form 106 on reaction with acrolein (Scheme ),100 while Otera and co‐workers101 developed a one‐pot double elimination protocol with sulfone 108 that gave 106 in good yield (Scheme 25 B) 102…”

“…Es wurde in jüngster Zeit mehrfach als Zielverbindung gewählt, um neue Methoden zur Synthese konjugierter Diine zu testen (Schema ). So erzeugten Ziegler et al aus 107 ein Phosphacumulenylid, das mit Acrolein zu 106 reagierte (Schema ),100 während Otera und Mitarbeiter101 ein Eintopfverfahren für die doppelte Eliminierung aus dem Sulfon 108 vorstellten, das 106 in guter Ausbeute ergab (Schema ) 102…”

“…[1][2][3][4][5][6] The design of multicomponent syntheses often relies on the integration of multiple individual reactions to give a one-pot synthetic operation, a new concept with important economical and environmental issues. [7][8][9][10] The chemistry and pharmacology of pyridazine derivatives have recently received considerable interest. This can be realized from the vast number of articles and patents published in the synthesis, chemistry, and biological activities of pyridazines.…”
