Optically active 4-diethoxyphosphinyl-3-(1-hydroxyethyl)-2-azetidinone (8) was synthesized from (2R,3R) N-diethoxyphosphinylmethyl-2,3-epoxybutyramide derivatives, and compound 8 was alternatively synthesized from (3R,4R)-4-acetoxy-3-[(R)-1-(t-butyldimethylsilyloxy)ethyl]-2-azetidinone via 3-[1-(t-butyldimethylsilyloxy)ethyl] derivative.
光学活性 4-二乙氧基膦酰基-3-(1-羟乙基)-2-氮杂环丁酮(8)由(2R,3R) N-二乙氧基膦酰甲基-2,3-环氧丁酰胺衍生物合成、而化合物 8 则是由(3R,4R)-4-乙酰氧基-3-[(R)-1-(叔丁基二甲基硅氧基)乙基]-2-氮杂环丁酮通过 3-[1-(叔丁基二甲基硅氧基)乙基]衍生物合成的。
