Phosphonoacetamide esters bound to solid supported peptides or peptide synthesis supports are active as Horner-Wadsworth-Emmons (HWE) reagents with a variety of aldehydes. HWE reagents can be attached to the solid support via the amide or phosphono ester. Mild basic conditions, triethylamine and Li salts, with excess aldehyde give high conversions to alkenes.
结合到固体支持的肽或肽合成支持物上的磷乙酰胺酯作为具有多种醛的Horner-Wadsworth-Emmons(HWE)试剂具有活性。HWE试剂可以通过酰胺或膦酰基酯连接到固体支持物上。温和的碱性条件,三乙胺和锂盐以及过量的醛会使烯烃高转化率。
