α-Xanthylmethyl Ketones from α-Diazo ketones
López-Mendoza, Pedro,Miranda, Luis D.
, p. 3777 - 3790 (2021/07/07)
A simple and efficient method to obtain α-xanthylmethyl ketones from α-diazo ketones is described. The reaction proceeds through a protonation/nucleophilic substitution sequence in the presence of p -toluenesulfonic acid and potassium ethyl xanthogenate as the nucleophile. As α-diazo ketones can be readily synthesized from ubiquitous carboxylic acids, a broad variety of xanthates can be obtained, including examples from naturally occurring substrates.

Synthesis of di- and tri-substituted fluoroalkylated azepanes was achieved by ring expansion of pyrrolidines via a regioselective attack of nucleophiles on a bicyclic azetidinium intermediate. A broad scope of azepanes, substituted at C4 and bearing a α-t
