Abstract Arylurea and their analogues have been one of the most ubiquitous backbone during the past century, and extensive studies have been conducted to establish practical synthetic methods for their derivatives. In particular, it is an effective pathway to synthesize arylureas by using commercially available phthalimide compounds. Reported herein is a triethoxyphosphine promoted ring-opening of the N-hydroxyphthalimide
摘要 芳基脲及其类似物在过去的一个世纪中一直是最普遍的骨架之一,并且已经进行了广泛的研究以建立其衍生物的实用合成方法。特别是利用市售邻苯二甲酰亚胺化合物合成芳基脲是一种有效途径。本文报道了三乙氧基膦通过胺的亲核攻击促进 N-羟基邻苯二甲酰亚胺 (NHPI) 的开环。这种转化在温和的反应条件下显示出广泛的官能团耐受性。
