Enamines of type 1 with anion-stabilizing substituents a are available by Horner-reaction of suitable phosphonates with 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
具有阴离子稳定取代基α的1型烯胺可通过合适的膦酸酯与醛的霍纳反应获得。1的去质子化反应得到氨基烯丙基阴离子2,它与羰基化合物(取决于a)反应生成丁内酯8。10或6元内酯13。该过程相当于由两个羰基化合物和一个α-氨基取代的膦酸酯合成内酯。
