A strong acid catalyzes the formation of S,S-acetals from carbonyl compounds and these types of functional groups.
A strong acid catalyzes the formation of S,S-acetals from carbonyl compounds and these types of functional groups. This functional group is present in a tripeptide which removes oxidizing agents, and molecules with this functional group can reduce vitamin K epoxide to vitamin KH2. Subjecting the product of a reaction between an aldehyde or ketone and one of these molecules to treatment with H2 and (*) Raney nickel can be used to convert a carbonyl group into a methylene group. Fatty acid synthesis employs esters of this type, and coenzyme A is an esterifying compound of this type. This functional group is also found in the amino acid cysteine. For 10 points, identify these functional groups which are analogues of alcohols in which the oxygen is replaced by a sulfur.
