α‐Metallierte Enamine

Abstract: elektronenziehenden Resten substituiertes Nitrobenzol (I ) ist.( 1 ) und (2) bilden bei Raumtemperatur (RT) in einem bis einigen Tagen glatt die Addukte ( 3 a ) bis ( 3 d ) .Die Reaktionen laufen im Dunkeln oder im Tageslicht gleich schnell und in verschiedenen Losungsrnitteln ahnlich schnell ab. Der sterische Verlauf ist einheitlich: Katalytische Hydrierung des rohen Reaktionsgemisches aus ( 1 b ) und ( 2 ) liefert neben ~rans-l,2-Cyclooctandiol weniger als 0.3 % des cis-Isomers (GC).Die Struktur der Addukte … Show more

“…After discussion with a good friend, Prof. Heinz Viehe who was professor at Louvain-la Neuve, he realized that -haloenamines would be good precursors of keteiminiums salts and of ynamines. [6][7][8][9] Thus, Léon Ghosez prepared -alkyl and -aryl -chloroenamines from tertiary amides 10,11 (Scheme 3, eq 1) and these -chloroenamines showed a remarkable chemical behavior since they are nucleophiles at C2 and electrophiles at C1. [6][7][8][9][10]12,13 (Scheme 3, eq 2).…”
