Diastereo- and enantioselective synthesis of 5-(1′-hydroxyalkyl)-3-methylidenetetrahydro-2-furanones from 2-diethoxyphosphoryl-4-alkenoic acids or 2-diethoxyphosphoryl-4-alkenoates was readily accomplished using novel methodology involving syn- or anti-dihydroxylation procedures combined with Horner–Wadsworth–Emmons olefination techniques.
Diastereo-和5-对映选择性合成(1'-羟基烷基)-3- methylidenetetrahydro -2-呋喃酮由2-二乙氧基磷酰基-4-链烯酸或2-二乙氧基磷酰基-4-烯酸酯使用涉及新颖的方法可以容易地完成顺式-或反-二羟基化方法与Horner-Wadsworth-Emmons烯化技术相结合。
