Spiro oxazolidinediones (2) derived from five- and six-membered ring aralkyl ketones are potent aldosereductaseinhibitors in vitro and in vivo. Their novel and general synthesis has been devised with alpha-hydroxyimidates (5) and 4-alkoxy-2-oxo-3-oxazolines (6) as key intermediates, since traditional synthetic routes through alpha-hydroxy amides (8) usually led to alpha, beta-unsaturated amides (9)
