Spiro oxazolidinediones (2) derived from five- and six-membered ring aralkyl ketones are potent aldose reductase inhibitors 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)
衍生自五元和六元环芳烷基酮的螺恶唑烷二酮(2)是体外和体内有效的醛糖还原酶抑制剂。他们设计了新颖且通用的合成方法,因为α-羟基亚氨酸盐(5)和4-烷氧基-2-氧代-3-恶唑啉(6)是关键中间体,因为传统的合成途径通常是通过α-羟基酰胺(8)生成α ,β-不饱和酰胺(9)。用辛可尼定拆分得到旋光的螺恶唑烷二酮。最佳生物活性存在于(4S)-6-氯螺[4H-2,3-二氢苯并吡喃-4,5'-恶唑烷] -2',4'-二酮(21)及其6,8-二氯同类物(23)中。
