Bis-BINOL derivatives have proven highly useful in applications such as chemosensing or organocatalysis. In this account, we describe strategies for the linking of BINOL units via the 3-, 4-, or 5-positions, showing that unique synthetic strategies are necessary to address each position. We report the synthesis of suitable C 1-symmetric precursors, which are generated either by monohalogenation or by monodeprotection of C 2-symmetric starting materials, and their subsequent coupling to give linked bis-BINOL derivatives.

Bis-BINOL衍生物的合成:通过生成合适的C 1对称前体,通过3位,4位或5位连接

已证明Bis-BINOL衍生物在化学传感或有机催化等应用中非常有用。在此说明中,我们描述了通过3位,4位或5位BINOL单元连接的策略,表明独特的合成策略对于解决每个位置都是必要的。我们报道了合适的C 1-对称前体的合成,其通过C 2-对称起始原料的单卤代反应或通过单脱保护而产生,并且其随后偶联以产生连接的双-BINOL衍生物。
