adequately protecting it against cellular nucleophiles. This design preserves the low steric profile of an alkyne and pairs it with a comparably unobtrusive hydroxylamine. The kinetics are on par with those of the fastest strain-promoted azide-alkyne cycloaddition reactions, the products regioselectively formed, the components sufficiently stable and easily installed, and the reaction suitable for cellular
N , N之间的生物正交反应描述了-二烷基羟胺和推拉活化卤代炔烃。我们探索了再杂化效应在激活炔烃中的应用,并且我们表明,当竞争的立体电子和感应因子得到适当平衡时,电子效应在未催化的共轭逆 Cope 消除反应中充分激活线性炔烃,同时充分保护其免受细胞亲核试剂的侵害。这种设计保留了炔烃的低空间分布,并将其与相对不显眼的羟胺配对。动力学与最快的应变促进叠氮化物-炔烃环加成反应相当,产物区域选择性形成,组分足够稳定且易于安装,反应适合细胞标记。

The structure and reactivity of intermediate propargylindium complexes have been investigated. Their reaction with electrophiles produced a difluoroalkyne or -allene, depending on the nature of the electrophiles. A mechanism based on the Curtin-Hammett principle was invoked to explain this phenomenon. A newly proposed mechanism on the formation of indium(III) complexes, through the intermediacy of
