Sulfones and sulfoxides synthesised from methionine and homocysteine thiolactone have been cyclised to amino ketones using potassium bis(trimethylsily)amide. Ramberg-Bäcklund chemistry on one of the sulfones gave an amino cyclopentenone whereas acyclic α-amino ketones and anti-amino alcohols were obtained by Raney nickel desulfurisation of the sulfoxides.
