unusual adduct, are obtained from the title compounds. 3-Alkoxy-3-benzyl-2-phenylphthalimidines 3 are synthesized. The behaviour of 1, 3-benzylidene-2-phenylphthalimidines (4 and 5), 3-(α-bromobenzylidene)-2-phenylphthalimidines (6 and 7) with respect to bases and the preparation of the open tautomer 13 of 1 and its hydrochloride are described. A hypothetical mechanism about the formation of 1 and

it! An intramolecularcyclization reaction of o‐alkynylbenzamides that allows dichotomouscontrol of E/Z‐geometry has been developed using an organicsuperbase, P4‐tBu, as a catalyst. The presence/absence of water along with the use of an organicsuperbase provides the necessary control of the geometry at the exo‐double bond. The method enables efficient access to isoindolinone derivatives, an important
E / Z 做到了!邻炔基苯甲酰胺的分子内环化反应可实现E / Z几何形状的二分控制,已使用有机超碱P4- t Bu作为催化剂进行了开发。水的存在与否以及有机超碱的使用为exo- double键的几何形状提供了必要的控制。该方法能够有效利用异吲哚啉酮衍生物,这是一类重要的生物活性分子。
