N-Substituted Lithium 2-Lithioallylamines: New Intermediates in Synthesis

Barluenga, Jose,Foubelo, Francisco,Fananas, Francisco J.,Yus, Miguel

, p. 553 - 557 (2007/10/02)

N-Phenyl or N-benzoyl 2-halogenoallylamines (5) or (10) react successively with phenyl-lithium and lithium naphthalenide at -78 deg C to give the intermediates (4) or (11), which on reaction with electrophiles (water, deuterium oxide, dimethyl disulphide, aldehydes, ketones, or allyl bromide) yield functionalized allyl amines (6) and (12).The corresponding N-alkyl derivatives (9) afford prop-2-ynylamines (8) under the same reaction conditions.
