Polyhydroxylated pyrrolidines have been synthesized in a one-pot procedure by the addition of an organometallic reagent to isoxazolidines obtained by a 1,3-dipolar cycloaddition between nitrones and vinylsulfones. This method highlights sulfone reactivity and provides an easy approach for the preparation of chiral pyrrolidines using cyclic imines as key intermediates.
多羟基化的吡咯烷是通过一锅法通过将有机金属试剂添加到异恶唑烷中而合成的,该异恶唑烷是通过在硝酮和乙烯基砜之间进行1,3-偶极环加成而获得的。该方法突出了砜的反应性,并为使用环状亚胺作为关键中间体制备手性吡咯烷提供了简便的方法。
