stepwise cyclization involving a sequential ring opening of aziridines and Pictet–Spengler reaction has been developed for the synthesis of 4-spiroannulated tetrahydroisoquinoline compounds (22 examples). The novel features of this strategy include high bonding efficiency and cyclization efficiency, broad substrate scope, mild conditions and good generality of the ring size in the product.
已经开发了涉及氮丙啶的顺序开环和 Pictet-Spengler 反应的逐步环化,用于合成 4-螺环化四氢异喹啉化合物(22 个例子)。该策略的新特点包括键合效率和环化效率高、底物范围广、条件温和以及产物中环尺寸的通用性好。
