Enamines of type 1 with anion-stabilizing substituents a are available by Horner-reaction of suitable phosphonates aldehydes.Deprotonation of 1 gives aminoallyl anions 2, which react with carbonyl compounds (depending on a) either to butyrolactones 8 resp. 10 or to 6-membered lactons 13.This process amounts to synthesis of lactones from two carbonyl compounds and an α-aminosubstituted phosphonate.
