practical and efficient method to access polysubstituted aryl sulfides has been discovered via a Lewis acid-catalyzed reaction between alkynyl sulfide and 2-pyrone, involving a Diels–Alder/retro-Diels–Alder pathway. Alkynyl sulfide as an electron-rich dienophile and 2-pyrones as electron-poor dienes are conjunctively transformed into a series of polysubstituted aryl sulfides with broad functional group compatibility
通过炔基硫醚和 2-吡喃酮之间的路易斯酸催化反应,发现了一种实用且有效的获取多取代芳基硫醚的方法,涉及 Diels-Alder/retro-Diels-Alder 途径。作为富电子亲二烯体的炔硫醚和作为缺电子二烯的2-吡喃酮联合转化为一系列具有广泛官能团相容性的多取代芳基硫醚,产率良好到优异(40个例子,产率43-88%)。该协议的稳健性和实用性已通过克级合成和所得产品的易于转化得到证明。
