A novel and improved synthetic route for the preparation of the new alkaloid setigerine, isolated from Papaver setigerum DC, and some new 3,4-dihydropapaverine and papaverine derivatives is reported. This method is based on the side chain chlorination of 1-benzyl-3,4-dihydroisoquinolines using N-chlorosuccinimide (NCS) and subsequent reaction with sodium methoxide in methanol to give the corresponding
报道了一种新颖的,改进的合成路线,用于制备从罂粟分离的DC,以及一些新的3,4-二氢罂粟碱和罂粟碱衍生物。该方法基于使用N-氯代琥珀酰亚胺(NCS)对1-苄基-3,4-二氢异喹啉进行侧链氯化,然后与甲醇钠在甲醇中反应,得到相应的异喹啉。
