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.
由甲硫氨酸和高半胱氨酸硫代内酯合成的砜和亚砜已使用双(三甲基甲硅烷基)氨基钾环化成氨基酮。用一种砜进行Ramberg-Bäcklund化学反应可得到氨基环戊烯酮,而无环α-氨基酮和抗氨基醇则是通过阮内镍对亚砜进行脱硫而得到的。
