The disclosure is concerned with providing phosphonic acid-containing derivatives of phenylalanine and optically active isomers thereof, which are functionalized in a manner which makes them suitable for facile incorporation into peptides using standard solid-phase or solution-phase techniques. The disclosure is also concerned with providing an advantageous one-step reaction method for preparing benzylic .alpha.,.alpha.-difluorophosphonates from corresponding benzylic ketophosphonates.
该公开涉及提供含有膦酸衍生物的苯丙氨酸及其光学活性异构体,这些衍生物以一种使它们适合通过标准固相或溶液相技术轻松地纳入肽中的方式进行官能化。该公开还涉及提供一种有利的一步反应方法,用于从相应的苯基酮膦酸酯制备苄基α,α-二氟膦酸酯。
