A convenient procedure for the preparation of carbamate derivatives of 5-oxo-2,5-dihydrofuran (3) was described. The method is based on the Michael type addition of three alkyl carbamates (2) with 4-acetyl-5-methyl-2,3-dihydro-2,3-furandione (1). According to 1H nmr spectra of compounds show tautomeric forms (3,4,5) in CDC13. In the solid state the synthesized compounds are enol forms (3). The products
描述了制备5-氧代-2,5-二氢呋喃(3)的氨基甲酸酯衍生物的简便方法。该方法基于三个氨基甲酸烷基酯(2)与4-乙酰基-5-甲基-2,3-二氢-2,3-呋喃二酮(1)的迈克尔型加成。根据1 H nmr光谱,化合物在CDC1 3中显示互变异构形式(3,4,5)。在固态下,合成的化合物为烯醇形式(3)。用分子光谱法表征产物。

Optimization of the novel alpha-2-delta-1 ligand 4 provided compounds 37 and 38 which have improved DMPK profiles, good in vivo analgesic activity and in vitro selectivity over alpha-2-delta-2. An in-house P-gp prediction programme and the MetaSite (R) software package were used to help solve the specific problems of high P-gp efflux and high in vivo clearance. (C) 2010 Elsevier Ltd.
