A methodological study devoted to the Mannich-like multicomponent synthesis of the antiplatelet agent (±)‑clopidogrel (7) and the ethyl ester analogue 6 is described. The process involves the formation of 2-chlorophenyl zinc bromide (2) and its subsequent reaction with an alkyl glyoxylate and 4,5,6,7-tetrahydrothieno[3,2-c]pyridine (3). We demonstrate that the organozinc reagent 2 also constitutes a very convenient nucleophile for the multicomponent synthesis of the benzylamine core of ticlopidine (9).
本研究描述了抗血小板药物(±)-氯吡格雷(7)和乙酯类似物 6 的曼尼希式多组分合成方法。合成过程包括生成 2-氯苯基溴化锌 (2),然后与乙醛酸烷基酯和 4,5,6,7-四氢噻吩并[3,2-c]吡啶 (3) 反应。我们证明,有机锌试剂 2 也是一种非常方便的亲核剂,可以多组分合成噻氯匹定的苄胺核心 (9)。
