(R)-4-Benzylthiazolidine-2-thione (cas: 110199-17-2) belongs to thiazolidine derivatives. Thiazolidines undergo hydrolysis to aldehyde and amino thiol under acid or basic aqueous conditions. Thiazolidine is prepared as it was in its first reported synthesis, by the condensation of cysteamine and formaldehyde. Other thiazolidines may be synthesized by similar condensations. A notable derivative is 4-carboxythiazolidine, derived from formaldehyde and cysteine.Reference of 110199-17-2

Total synthesis and structural validation of cyclodepsipeptides solonamide A and B was written by Kitir, Betul;Baldry, Mara;Ingmer, Hanne;Olsen, Christian A.. And the article was included in Tetrahedron in 2014.Reference of 110199-17-2 This article mentions the following:

Microorganisms are an attractive source of new natural products with antimicrobial properties, and the marine environment constitutes a prolific resource of bioactive microorganisms. During a global research expedition (Galathea III), two depsipeptides, solonamide A and solonamide B, were isolated from the marine bacterium Photobacterium halotolerance and were found to inhibit virulence gene expression in the serious human pathogen, Staphylococcus aureus. They act by interfering with the agr quorum sensing system and show resemblance to the endogenous S. aureus quorum sensing peptide, autoinducing peptide I (AIP-I). To enable more comprehensive studies, we embarked on the chem. synthesis of solonamides A and B. The key synthetic steps were formation of the (R)-β-hydroxy-fatty-acids by stereoselective aldol reactions and a cyclative macrolactamization, which proceeded under highly dilute conditions. Thus, the first total syntheses of the solonamides corroborated the originally assigned structures, and by changing the stereochem. of the auxiliary in the aldol steps we gained access to the natural products as well as their β3-epimers. In the experiment, the researchers used many compounds, for example, (R)-4-Benzylthiazolidine-2-thione (cas: 110199-17-2Reference of 110199-17-2).
