Intermolecular transaminations of enaminones: a synthesis of fused, polycyclic, N-aryl pyridones
摘要:
Aryl amines reacted with enaminones like (2-chloro-3-pyridinyl)[2-(1-pyrrolidinyl)-1-cyclopenten-1-yl]methanone, and the transaminated products cyclized to aryl-substituted pyridones like 6,7,8,9-tetrahydro-9-phenyl-5H-cyclopenta[b][1,8]naphthyridin-5-one. The starting enaminones rearranged thermally, also forming pyridones, for example 9-(4-chlorobutyl)-6,7,8,9-tetrahydro-5H-cyclopenta[b][1,8]naphthyridin-5-one.
