An efficient stereoselective synthesis of (+)-deoxoprosophylline from readily available p-anisaldehyde is described. Key steps in the synthesis include the stereoselective amination of anti-1,2-dibenzyl ether using chlorosulfonyl isocyanate, intermolecular olefination, and Pd-catalyzed intramolecular cyclization.
描述了从容易获得的对-茴香醛有效地立体选择性合成(+)-脱氧代茶碱。合成的关键步骤包括使用氯磺酰基异氰酸酯对抗-1,2-二苄基醚进行立体选择性胺化,分子间烯化和Pd催化的分子内环化。
