unprecedented cascade reaction of benzoyl sulfoxonium ylides with α-diazocarbonyl compounds leading to the formation of highly functionalized naphthalenones containing a β-ketosulfoxonium ylide moiety is presented. Promisingly, the naphthalenone derivative thus obtained was found to be a versatile intermediate toward diversely functionalized naphthalene derivatives including substituted 1-naphthol,
提出了空前的苯甲酰基硫代亚砜基化物与α-重氮羰基化合物的级联反应,导致形成高度功能化的含有β-酮基硫代氧鎓叶立德部分的萘烯。很有希望地发现,如此获得的萘酮衍生物是向多种官能化的萘衍生物的通用中间体,所述萘衍生物包括取代的1-萘酚,2-羟基萘-1(2H)-,萘-1,2-二酮和2-(甲基亚磺酰基)。萘-1-醇。
