Reaction of nitroalkylideneoxindoles with selected activated carbonyl compounds under Morita–Baylis–Hillman (MBH) conditions (DABCO/CH3CN) led to unexpected formation of Wittig type products. While the first two steps involve MBH pathway (Michael addition and aldol reaction), the subsequent steps in this one‐pot process are presumably intramolecular substitution and elimination.

威蒂希产品的Morita–Baylis–Hillman途径:硝基亚烷基氧杂吲哚的一锅法转化为亚氧杂环丁二烯-羧酸盐

在Morita–Baylis–Hillman(MBH)条件(DABCO / CH 3 CN)下,硝基亚烷基新吲哚与选定的活化羰基化合物的反应导致了Wittig型产物的意外形成。尽管前两个步骤涉及MBH途径(迈克尔加成反应和羟醛反应),但此一锅法过程中的后续步骤可能是分子内取代和消除。
