Abstract
|
|
|
|
| A convenient synthesis of alpha-diones and their monoprotected acetals, i.e. alpha-ketoacetals, was developed by mercury induced solvolysis of regiospecifically formed alpha-chloro-alpha-(alkylthio)ketones. Analogously, alpha-alkoxy-alpha-sulfenylated ketones were formed when reacting alpha-chloro-alpha sulfenylated ketones with an alkaline alcoholic medium. alpha-Alkoxy-alpha-sulfenylated ketones themselves could be transformed into alpha-diones or alpha-ketoacetals, which in turn were hydrolyzed under anhydrous conditions into the corresponding alpha-diones.
