Tandem reactions using base‐promoted processes have been developed for the synthesis of xanthone and chromone derivatives. The first examples of base‐promoted insertion reactions of isolated carbon–carbon triple bonds into carbon–carbon σ‐bonds have been reported. Using these approaches, polycyclic structures can be prepared. This reaction has the potential to become a general synthetic protocol for the preparation of multi‐substituted xanthones and chromones due to the abundance of easily accessible starting materials possessing diverse substituent groups.

碱促进的串联反应，涉及插入碳-碳σ-键中：th吨酮和色酮衍生物的合成

已经开发了使用碱促进方法的串联反应，用于合成黄酮和色酮衍生物。已经报道了由碱促进的分离的碳-碳三键成碳-碳σ键的插入反应的第一个例子。使用这些方法，可以制备多环结构。该反应有可能成为制备多取代的氧杂蒽酮和色酮的通用合成方法，这是由于具有各种取代基的易于获得的起始原料的丰富性。
