| | 2,5-Dihydroxy-1,4-dithiane Usage And Synthesis |
| Chemical Properties | white to yellowish crystalline powder | | Chemical Properties | 2,5-Dihydroxy-1,4-dithiane has a sulfurous, meaty, toasted bread-like odor | | Uses | 1,4-Dithiane-2,5-diol is a hydroxylated dithiane derivative with phytogrowth-inhibitory and antibacterial activities. | | Uses | 1,4-Dithiane-2,5-diol was used in the synthesis of:
- substituted tetrahydrothiophene derivatives
- 2-amino-3-(arylsulfonyl)thiophenes, potential antiviral and antitumor agents
| | Definition | ChEBI: 1,4-Dithiane-2,5-diol is a member of dithianes. | | Aroma threshold values | Aroma characteristics at 0.1% EtoH: sulfurous, grilled meaty, pungent, brothy, eggy, heavy and rich,
toasted bread, tomato | | Taste threshold values | Taste characteristics at 0.25 to 10 ppm: metallic, meaty savory chicken and beef, sulfurous,
egg-yolk-like | | Synthesis Reference(s) | Synthetic Communications, 14, p. 483, 1984 DOI: 10.1080/00397918408059569 | | General Description | 1,4-Dithiane-2,5-diol undergoes bifunctional squaramide catalyzed sulfa-Michael/aldol cascade reaction with chalcones to afford trisubstituted tetrahydrothiophenes. It participates in diastereoselective [3+3] cycloaddition with azomethine imines catalyzed by 1,4-diazabicyclo[2.2.2]octane. It is a mercaptoacetaldehyde dimer and an efficient synthon for incorporating a thiol group to in situ generated nitroalkenes. |
