Reformatskyreactions of p-quinones with crystalline reagent (BrZnCH2CO2Et·THF)2 were investigated and took place successfully, providing β-hydroxy esters in high yield. Notably, in the case of 2,6-disubstituted-p-quinones, regioselective Reformatskyreactions occurred to give corresponding β-hydroxy esters in good yields.
研究了对苯醌与结晶试剂(BrZnCH 2 CO 2 Et·THF)2的重整反应,并成功进行,从而以高收率提供了β-羟基酯。明显地,在2,6-二取代的对苯醌的情况下,发生区域选择性的Reformatsky反应以良好的产率得到相应的β-羟基酯。
