3-烷基(芳基甲基)氨基-2-重氮-3-氧代丙酸乙酯(重氮酰胺基乙酸酯)通常同时生成环庚[ c ]吡咯烷酮(Buchner产物)和β-内酰胺(1,4-插入产物),并显示出明显的N-铜盐催化下分子内布氏反应与脂肪族1,4-CH插入之间的取代基控制的化学选择性。酰胺部分中较少的空间N-烷基取代基通常有利于脂肪族1,4-CH插入,而较高的空间N-烷基取代基通常有利于布氏反应。与铑和钌催化的条件相比,当前的铜催化条件提高了3-烷基(芳基甲基)氨基-2-重氮-3-氧代丙酸乙酯的布氏反应选择性。

established reactions, their typical intolerance of water, especially at elevated temperatures (>100 °C), represents a key barrier to their mainstream adoption. Herein we report that FLPs based on the Lewis acid iPr3SnOTf are moisture tolerant in the presence of moderately strong nitrogenous bases, even under high temperature regimes, allowing them to operate as simple and effective catalysts for the reductive

A variety of secondary benzylic amines were oxidized to imines in 90% to >99% yields by singlet oxygen generated from oxygen and a porphyrin photosensitizer. On the basis of these reactions, a protocol was developed for oxidativeUgi-typereactions with singlet oxygen as the oxidant. This protocol has been used to synthesize C1- and N-functionalized benzylic amines in up to 96% yields.
