The present disclosure relates to a method for preparing various physiologically active pharmaceutical ingredients, such as a 1,1-diaryl compound and a 1,1-diheteroaryl compound (specifically, a 1,1-diaryl carbonyl compound), in an economical and convenient manner under mild conditions without using an expensive transition metal catalyst by activating an alkyne compound (e.g., an ynamide) using a Brønsted acid as a catalyst to induce a reaction of the activated alkyne compound and a N—O bond oxidant to form an adduct intermediate and then inducing a coupling reaction of the adduct intermediate with various nucleophilic organic compounds (e.g., a nucleophilic arene compound).
本公开涉及一种制备各种生理活性药用成分的方法,例如一种1,1-二芳基化合物和一种1,1-二杂芳基化合物(具体来说,一种1,1-二芳基酰基化合物),在温和条件下以经济和便捷的方式进行,而不使用昂贵的过渡金属催化剂,通过使用Brønsted酸作为催化剂激活炔烃化合物(例如,炔胺)来诱导激活炔烃化合物和N-O键氧化剂的反应形成加合物中间体,然后诱导加合物中间体与各种亲核有机化合物(例如,亲核芳烃化合物)的偶联反应。
