A novel transformation of N-alkoxycarbonylprolines 1 to 4-trifluoroacetyl-2,3-dihydropyrroles 2 was efficiently realized by utilizing trifluoroacetic anhydride, in which probable intermediates were mesoionic 1,3-oxazolium-5-olates B.
一种新颖的N-烷氧基羧基脯氨酸1转化为4-三氟乙酰基-2,3-二氢吡咯2的反应有效地通过利用三氟乙酸酐实现,其中可能的中间体为梅索离子1,3-噁唑鎓-5-醇酸盐B。
