The synthesis of a new endo-calix[4]naphthalene is described. The reaction sequence involves the cyclocondensation of a key bisnaphthylmethane intermediate (8) with formaldehyde. This key intermediate (8) is formed using a modified Suzuki-Miyaura Pd-catalyzed cross-coupling reaction between bromomethylnaphthyl (6) and naphthylboronic acid (7), both of which can be derived from 2-hydroxynaphthoic acid
描述了新的内杯[4]萘的合成。反应顺序包括关键的双萘甲烷中间体(8)与甲醛的环缩合。该关键中间体(8)是使用改良的Suzuki-Miyaura Pd催化的溴甲基萘基(6)和萘基硼酸(7)之间的交叉偶联反应形成的,两者均可衍生自2-羟基萘甲酸。
