A methodology for the synthesis of 7,12-dihydro-5H-6,12-methanodibenzo[c,f]azocines from aromatic aldehydes and N-(methoxymethyl)-N-(trimethylsilylmethyl)benzylamine using catalysis by trifluoroacetic and perchloric acids is described. The developed protocol was applied for the synthesis of N-unsubstituted and N-methyl-4-aryltetrahydroisoquinolines.
描述了使用三氟乙酸和高氯酸催化从芳族醛和N-(甲氧基甲基)-N-(三甲基甲硅烷基甲基)苄胺合成7,12-二氢-5H-6,12-甲基二苯并[c,f]偶氮嗪的方法。该开发的方案适用于N-未取代和N-甲基-4-芳基四氢异喹啉的合成。
