Homoallylic Phosphonates: Useful Precursors for 3,4-Epoxyalkanephosphonates

Abstract

Exoxyalkanephosphonates are compounds of interest as potential drugs¹ or intermediates in various synthetic transformations^2. Especially 1,2-epoxyalkanephosphonates and 2,3-epoxyalkanephos-phonates attracted much attention and many preparatively useful routes to these compounds have been reported^3. On the other hand the synthesis of 3,4-epoxyalkanephosphonates has to our knowledge not been described∗.
