摘要
The sterically demanding 9-phenylfluorenyl N-protection of a number of amino acids allows the formation of amino acid derived beta-ketophosphonate reagents and their Horner-Wadsworth-Emmons olefination. In an attempt to develop a synthesis of Derythro-homosphingosine in enantiopure form, we have shown that the reactivity of the intermediates is influenced by the distinctive conformational requirements of this large protecting group.
