Open sesame: A direct synthesis of functionalised and stereodefined dienes, relying on a domino allylic alkylation/electrocyclic ring‐opening sequence, is reported. This method allows concise access to doubly vinylogous esters. A further systematic study of ring‐opening rates of carbon‐substituted cyclobutenes allowed the design of substrates amenable to sequential pericyclic reactions (see scheme)
芝麻开裂:据报道,依赖于烯丙基烯丙基烷基化/电环开环序列的功能化和立体定义的二烯的直接合成。该方法允许简洁地获得双乙烯基酯。碳取代的环丁烯的开环速率的进一步系统研究允许设计适用于连续环周反应的底物(参见方案)。
