Naphthalene catalysed reductive lithiation of various chloroazines (1, 7, 10, 13) in the presence of different electrophiles yields, after hydrolysis, the expected functionalised heterocycles with one (2, 8), two (11, 14a–d) and three nitrogen atoms in the ring (14e,f). This methodology allowed us to trap in situ the lithium imine derived from the reaction of 2-pyridyllithium with benzonitrile, by

The regioselective ring-opening of lactones (δ-valerolactone and γ-butyrolactone) with aryllithium reagents is reported for the construction of a series of δ-hydroxy aryl ketones and γ-hydroxy aryl ketones. Application of this method for the expeditious syntheses of (±)-anabasamine and its nicotine-related analogue are also described.
