Δ1-pyrrolines, Δ1-piperideines and 1-aza 1-cycloheptenes are formed in good yields from the decarboxylation of alkylated cyclic β-enaminoesters with boric acid.

The reaction of lactim ethers 1-3 with organolithium reagents has been found to be an effective method for the preparation of cyclic 2-alkyl imines 4-6.The method is most effective for the preparation of 2-aryl and sterically hindered 2-alkyl imines.In addition, treatment of 1-3 with excess organolithium provides a facile route to the rare cyclic 2,2-dialkyl amine derivatives 7-9.These reactions are characterized by mild reaction conditions and good yields and constitute a superior route to the title compounds.
