All-trans 1,3,4,5-tetrasubstituted γ-butyrolactams 3 and 7 are readily available in one-pot from allyl tetronates or 4-allyloxycoumarins and amines via a four-step domino Claisen–Conia ring-opening transamidation reaction.
全反式1,3,4,5-四取代的γ-丁内酰胺3和7可通过四步多米诺骨牌Claisen-Conia开环转氨反应一锅得自烯丙基四价酸酯或4-烯丙氧基香豆素和胺。
