reagents, namely, dn-alkyl sulfonium salts, dn-alkyl halides, a dn-alkyl azide, and a dn-alkyl amine, were prepared and used to efficiently introduce dn-alkyl groups into drug candidates and their analogues with complex skeletons. A liver microsomal metabolism study using 7-(d2-ethoxy)flavone as a model compound revealed a significant deuterium kinetic isotopeeffect due to the installed d2-ethoxy group
制备了多种氘化试剂,即dn-烷基锍盐、 dn-烷基卤化物、 dn-烷基叠氮化物和dn-烷基胺,并用于有效地将dn-烷基引入候选药物中,并它们的类似物具有复杂的骨架。使用 7-( d 2 -乙氧基)黄酮作为模型化合物进行的肝微粒体代谢研究表明,由于安装了d 2 -乙氧基,因此具有显着的氘动力学同位素效应。

Nineteen new N,N'-disubstituted phthalidyl spirohydantoins (6a-s) were prepared for the purpose of pharmacological testing. Their structure was deduced from the IR, H-1-NMR, C-13-NMR, mass spectra and elemental analysis. The two possible structural isomers - only one of which is formed - can be distinguished unequivocally on the basis of selective diastercotopicity of the alpha-methylene hydrogens adjacent to N-3' of the hydantoin ring.
