A new class of pyridinium, quinolinium, isoquinolinum, and N-methylimidazolium-3-(2,5-dihydro-5-oxofuran-3-yl)-4-hydroxyfuran-2(5H)-one salts have been prepared in high yields by reacting pyridine, quinoline, isoquinoline, N-methylimidazole, 1,4-diazabicyclo[2.2.2]octane, and their derivatives with tetronic acid in CH2Cl2.
N -bromosuccinimide-promoted cyclization of -carboxymethyl enamino esters; Synthesis of functionalized 4-amino-2(5 H)-furanones

experimental part, p. 2781 - 2788 (2011/10/18)
An easy, two-step approach to various 5-carboxymethyl-2(5H)-furanones is described. A detailed study of the reaction of -carboxymethyl enamino esters with N-bromosuccinimide is presented. Georg Thieme Verlag Stuttgart - New York.
N-substituted tetronamides as ambident nucleophilic building blocks for the synthesis of new 4-aza-2,3-didehydropodophyllotoxins
Madec, David,Mingoia, Francesco,Prestat, Guillaume,Poli, Giovanni
scheme or table, p. 1475 - 1478 (2009/04/07)
Aza-analogues of podophyllotoxin were synthesized in two steps from N-substituted tetronamides. The acid-mediated benzhydrylation of N-substituted tetronamides with a suitably func-tionalized benzhydrol quantitatively afforded the cyclization precursors.
