In the presence of 2-(trimethylsilyl)aryl triflates as aryne precursors under mild conditions, a range of tertiary propargylic amines bearing electron-withdrawing groups were converted to quaternary propargylic ammonium ylides followed by a [2,3]-sigmatropic rearrangement to afford structurally diverse amino-substituted allenes or conjugated dienes, depending on their structure, in moderate to good
在2-(三甲基甲硅烷基)芳基三氟甲磺酸酯作为芳烃前体的条件下,在温和条件下,将一系列带有吸电子基团的叔炔丙基胺转化为季炔丙基戊基铵,然后进行[2,3]-σ重排,从而结构上得到取决于它们的结构,以中等到良好的收率得到各种氨基取代的烯或共轭二烯。
