3-Alkoxyoxazolidine-2,4-diones from N-Alkoxy-2-hydroxycarboxamides and 1,1'-Carbonyldiimidazole

Geffken, Detlef

, p. 817 - 825 (2007/10/02)

Reaction of N-alkoxy-2-hydroxycarboxamides 3 with 1,1'-carbonyldiimidazole produces N-alkoxyoxazolidine-2,4-diones 4.Hydrolysis of N-(tetrahydro-2H-2-pyranyloxy)oxazolidine-2,4-diones affords 3-hydroxyoxazolidine-2,4-diones 5 which are converted by the reaction with phenyl isocyanate into 7 and with benzoyl chloride into 8.Benzylaminolysis of 4 gave 3-benzyloxazolidine-2,4-diones 10.
