Spontaneous formation of diastereoisomeric 2-methylthiazolidine-2,4-dicarboxylates from cystine esters and related compounds

Dialkyl esters of cystine and lanthionine undergo conversion to cis- and trans-2-methylthiazolidine-2,4-dicarboxylates at 25-80°C in protic solvents.

Reaction of hydrogen sulfide with disulfide and Sulfenic acid to form the strongly Nucleophilic Persulfide

Background: Hydrogen sulfide (H2S) modulates physiological processes in mammals. Results: The reactivity of H2S toward disulfides (RSSR) and albumin sulfenic acid (RSOH) to form persulfides (RSSH) was assessed. Conclusion: H2S is less reactive than thiols. Persulfides have enhanced nucleophilicity. Significance: This kinetic study helps rationalize the contribution of the reactions with oxidized thiol derivatives toH2S biology.

A new approach to reductive deprotection of thioethers with a low-valent titanium reagent

Low-valent titanium mediated cleavage of carbon-sulphur bond is reported. This has resulted in an efficient and mild protocol for the deprotection of allyl/benzyl thioethers under reductive condition and with good yields. Deprotection can be performed regio- and chemo-selectively in the presence of acid, ester and N-benzyl/allyl functionalities and is general for aliphatic and aromatic precursors.
