环丁烯酮是一种带有不饱和碳-碳双键的四元酮类化合物,其结构兄弟苯并环丁烯酮具有独特的反应活性。由于其固有的高环应变,这种结构很容易在各种条件下进行开环,包括热分解、光解和过渡金属催化,以提供活性中间体,这些中间体可以被亲核试剂、亲二烯试剂和不饱和键捕获。它们的缺电子烯酮部分是很好的亲电试剂,便于亲核加成。这样的性质使得环丁烯酮是通用的合成物,在大量有价值的合成转换中作为优秀的耦合伙伴。
Cyclobutenones, four-membered ketones bearing an unsaturated carbon–carbon double bond, and their structural sibling benzocyclobutenones, possess unique reactivity. Owing to their inherent high ring strain, such structures readily undergo ring opening under a variety of conditions, including thermolysis, photolysis, and transition metal catalysis, to afford reactive intermediates that can be trapped with nucleophiles, dienophiles, and unsaturated bonds. Their electron-deficient enone moieties are good electrophiles for facile nucleophilic addition. Such properties render cyclobutenones versatile synthons, serving as excellent coupling partners in a vast array of synthetically valuable transformations.
