unsymmetrical 2,2′-binaphtyl derivatives, substituted on positions adjacent to the ring linkage are obtained by a one pot sequence: -bromophenylketone coupling with aryl ketone derived enolates under SRN1 conditions followed by an intramolecular aldol reaction. Steric hindrance of the nucleophilic site is the main yield limiting factor of the first reaction and therefore of the overall yield of the
通过一个罐序列获得在邻环键的相邻位置上取代的苯基-2萘和不对称的2,2'-联萘基衍生物:-溴苯基酮与芳基酮衍生的烯酸酯在S RN 1条件下偶联,随后进行分子内羟醛反应。亲核位点的立体位阻是第一反应的主要产量限制因素,因此是标题联芳基的总产量的主要限制因素。
