borylation of propargylic acetates. The reaction is highly efficient, occurs under mild conditions, and is easy to scale up. The reaction is stereospecific and occurs with anti-SN2‘ displacement of the acetate by boron, which allows a transfer of chirality. Several transformations including propargylation and further additions highlight the synthetic utility of this reaction.
多取代的联烯基硼酸酯很容易通过炔丙基乙酸酯的铁催化硼酸化获得。该反应效率高,条件温和,易于放大。该反应是立体有择的,发生时乙酸盐被硼反-S N 2' 置换,从而允许手性转移。包括炔丙基化和进一步添加在内的几种转化突出了该反应的合成效用。
Synthesis of 4‐Phosphinylpyrrolidin‐3‐ones via [3+2] Cycloaddition of Nitrones with Phosphinylallenes
A variety of 4-phosphinylpyrrolidin-3-ones was prepared via a [3+2] cycloaddition between aryl aldonitrones and phosphinylallenes. The products were isolated as unique 4,5-trans diastereomers, in yields between 47% and 80%, over 23 examples. In the case of chiral racemic allenes, a 2:1 to 4:1 moderate 2,5-diastereoselectivity was observed. Under the reaction conditions, the cycloadducts directly undergo
