摘要
N-Benzyloxy-2-(diethoxyphosphoryl)pent-4-enamide (6) was prepared from ethyl diethoxyphosphorylacetate in a 3-step sequence. Oxidative cleavage of the terminal olefin of 6 with osmium tetroxide and sodium periodate afforded 1-benzyloxy-3-diethoxyphosphoryl-5-hydroxy-2-pyrrolidone (7). The first synthesis of racemic SF-2312 was achieved by treatment of 7 with trimethylsilyl bromide, followed by hydrogenolysis.
