Using a 4-step scheme, we have synthesized deuterium-labelled 17α-hydroxypregnenolone for use as internal standard for an isotope dilution/mass spectrometry plasma assay. 17α-Hydroxyprogesterone served as starting material. Its 17α-hydroxygroup was protected by tetrahydropyranylation. Introduction of deuterium by base-catalyzed enolization and protection of the 3-hydroxygroup by acetate formation yielded
使用 4 步方案,我们合成了氘标记的 17α-羟基孕烯醇酮,用作同位素稀释/质谱血浆分析的内标。17α-羟基孕酮作为原料。其 17α-羟基被四氢吡喃基化保护。通过碱催化烯醇化引入氘并通过乙酸形成保护 3-羟基产生 [2,2,4,21,21,21-2H6]3β,17α-dihydroxypregna-3,5-diene-20-one 3 -乙酸酯 17-四氢-吡喃基醚。在 3-烯的还原氘化和去除保护基团 [2,2,4,4,21,21,21-2H7] 后,得到 17α-羟基孕烯醇酮。© 1998 John Wiley & Sons, Ltd.
