In contrast to an earlier report, aldoximes can be deprotonated to their dianions and alkylated in high yield. In 1976, Kofronl and JungL reported that ketone oximes could be deprotonated and alkylated regiospecifically syn to the oxime hydroxyl. In his report, Kofron noted that "attempts to alkyla
Alpha ketoamides may be deprotonated twice with stronq base. The dianions so formed react with alkyl halides to yield cl-amid0 tertiary alcohols. The extended enolates of crotonic acid derivatives 'anb have become valuable reactive intermediates in the preparation of R,y-unsaturated carbonyl compou
Several years ago Hauser observed that treatment of aromatic ketoximes with two equivalents of strong base resulted in the formation of dianions which could be successfully alkylated on n carbon.L However, no information on the stereochemistry of the alkylated products was ever reported. We now wish
Lithium arene dianions derived of polycyclic aromatic hydrocarbons, such as naphthalene, anthracene, phenanthrene, fluoranthene, pyrene, chrysene and binaphtyl react cleanly with n-alkylfluorides to afford regiochemically controlled alkylated dihydroarenes after hydrolysis. These arene dianions can
