A highly diastereo- and enantioselective organocatalytic protocol for the synthesis of biologically important spirocyclopentaneoxindoles containing the oxime functional group from easily accessible 3-allyl-substituted oxindoles and nitroolefins has been developed by a one-pot Michael addition/ISOC/fragmentation sequence.
通过一锅迈克尔加成/ ISOC /片段化序列已开发出一种高度非对映体和对映体选择性的有机催化方案,用于从易于获得的3-烯丙基取代的羟吲哚和硝基烯烃合成含肟官能团的生物学上重要的螺环戊烷氧吲哚。
