B 3 NO 2六元杂环(1,3-二氧杂-5-氮杂-2,4,6-三硼烷= DATB),由三种不同的非碳2期元素组成,最近被证明是羧酸脱水缩合的强大催化剂酸和胺。然而,繁琐的DATB合成大大降低了其作为催化剂的用途,因此,实际上仍未探索环系统的固有化学性质。在此公开了一种通用且简便的合成策略,该策略利用含嘧啶的支架可靠地安装硼原子,从而以模块化的方式由廉价材料制成了一系列Pym-DATB。可溶性Pym‐DATB衍生物的鉴定可用于研究B 3 NO 2的动力学性质环系统,根据介质的不同,显示出不同的开环和开环行为。易于获取的Pym‐DATB证明了其作为脱水酰胺化的有效催化剂的实用性,具有广泛的底物范围和官能团耐受性,为试剂驱动的酰胺化提供了一种通用且实用的催化替代方法。
