A General Procedure for Intramolecular α-tert-Alkylation of Carbonyl Compounds
Mono‐ and bicyclic as well as spirocyclic carbonyl compounds can be prepared by intramolecular tert‐alkylation of olefins such as (1) with SnCl4. An O‐stannyl derivative and a carbenium ion are probably intermediates in the reaction, which should find application in terpene and steroid syntheses....
