• Synthesis of some N-methyl-1,2,3,4-tetrahydroisoquinolines by Friedel–Crafts cyclisation using benzotriazole auxiliary

  日期：——

  1-Hydroxymethylbenzotriazole reacts with phenylethylamines to give the respective N,N-bis(benzotriazol-1-ylmethyl)phenylethylamines, which are then subject to an intramolecular Friedel–Crafts cyclisation at room temperature to yield N-benzotriazol-1-ylmethyl-1,2,3,4-tetrahydroisoquinolines. These crystalline UV- and oxygen-stable products can be reduced at room temperature to the corresponding N-methyl-1,2,3,4-tetrahydroisoquinolines using NaBH4. The method offers an elegant approach to a wide range of N-methylated 1,2,3,4-tetrahydroisoquinolines since it can be applied not only for the synthesis of 1,2,3,4-tetrahydroisoquinolines with electron-donating substituents on the aromatic moiety, but also for deactivated derivatives. All steps involved work under very mild conditions in high to excellent yields.

  1-羟甲基苯并三氮唑与苯乙胺反应生成相应的N,N-双(苯并三氮唑-1-甲基)苯乙胺，然后在室温下进行分子内Friedel-Crafts环化反应，生成N-苯并三氮唑-1-甲基-1,2,3,4-四氢异喹啉。这些结晶的紫外光和氧气稳定产物可以在室温下用NaBH4还原成相应的N-甲基-1,2,3,4-四氢异喹啉。这种方法为合成广泛范围的N-甲基化的1,2,3,4-四氢异喹啉提供了一种优雅的途径，因为它不仅可以应用于具有电子供体取代基的芳香部分的1,2,3,4-四氢异喹啉的合成，还可以应用于去活化的衍生物。所有步骤均在非常温和的条件下进行，收率高至优秀。
• A Synthesis of Mono- and Dimethoxy-1,2,3,4-tetrahydroisoquinolines via Pummerer Reaction: Effects of Methoxyl Groups on Intramolecular Cyclization.

  日期：——

  A synthesis of 1, 2, 3, 4-tetrahydroisoquinolines (TIQs)(23) with one and two methoxyl groups at various positions of the benzene ring was achieved via the intramolecular cyclization of N-(aryl)methyl-2-(phenylsulfinyl)ethylamines (9) using the Pummerer reaction as a key step. The reaction was carried out by using trifluoroacetic anhydride (TFAA)(method A) of TFAA-BF3·Et2O (method B). The cyclization to 4-SPhTIQs (11) proceeded effectively when the reaction center at the benzene ring was electronically activated by a methoxyl group. In the reaction of the sulfoxide (9e) having two OMe groups at ortho- and para-positions a different cyclization reaction leading to a benzothiazepine (12) was observed, indicating that the high nucleophilicity of the benzene ring caused the unexpected reaction prior to the cyclization to 4-SPhTIQ (11e). The route starting from methoxylated benzaldehydes (5) was proved to provide an efficient and convenient method of TIQ synthesis which should be complementary to the well known Pictet-Spengler method.

  合成了1, 2, 3, 4-四氢异喹啉（TIQs）（23），在苯环的不同位置上含有一个或两个甲氧基，这一过程是通过N-(芳基) methyl-2-(苯基亚磺酰)乙胺（9）进行的，采用Pummerer反应作为关键步骤。反应使用了三氟乙酸酐（TFAA）（方法A）和TFAA-BF3·Et2O（方法B）。当苯环的反应中心被甲氧基电子激活时，4-SPhTIQs（11）的环化反应有效进行。在具有两个OMe基团的亚磺酰（9e）反应中，观察到了一种不同的环化反应，形成了苯并噻嗪啉（12），这表明苯环的高亲核性导致了在环化到4-SPhTIQ（11e）之前发生了意想不到的反应。以甲氧基化苯甲醛（5）为起点的合成路线被证明是一种有效便捷的TIQ合成方法，应该与众所周知的Pictet-Spengler方法相辅相成。
