对过氧化氢对烯基磷化合物的环氧化进行了系统的研究,结果表明,尽管烯基膦氧化物未能产生相应的环氧化物,但烯基膦酸酯或在α位具有苯基的次膦酸酯与H 2 O 2 / K 2 CO 3或烯基膦酸反应在α-或β-位具有脂族基的次膦酸与H 2 O 2 / Na 2 WO 4 / Et 3 N反应以产生高产率的相应环氧化物。

(PPARδ) agonist natural product phosphoiodyn A is the phosphonate core. Synthesis of simplified phosphonate esters 13 and 15 provide structurally novel, highlyselective and potent PPARδ agonists (EC50 = 78 and 112 nM, respectively). Further, both compounds demonstrate significant neuroprotective activity in an in vitro cellular model indicating that phosphonates may be an effective novel scaffold
