An organocatalytic modified Pudovikreaction between dialkyl or diaryl phosphites and α-haloketones was used to synthesize β-chloro-α-hydroxyphosphonates in high yields with very high regioselectivity and high stereoselectivity. Aliphatic, aromatic, and cyclic ketones could be used successfully. Under the optimized conditions it was possible to obtain enantiomerically enriched products with a combination
使用二烷基或二芳基亚磷酸酯与 α-卤代酮之间的有机催化改性 Pudovik 反应以高产率合成 β-氯-α-羟基膦酸酯,具有非常高的区域选择性和高立体选择性。可以成功使用脂肪族、芳香族和环状酮。在优化条件下,可以通过奎宁和化学计量外消旋碱的组合获得对映异构体富集的产物,但 ee 值仅上升至 40%。β-氯官能团的存在允许进一步合成所获得的羟基膦酸酯,这可用于靶向合成,因为这些化合物通常具有重要的生物活性。
