Description

6-Methyl-4-oxo-5,6-dihydro-4H-thieno[2,3-b]thiopyran-2-sulfonamide is a chiral optical reagent that can be used to determine the enantiomeric purity of butyric acid. The optical rotation of 6MTA is measured at different concentrations of butyric acid in hexane with an eluent of acetonitrile. It has been synthesized from a Grignard reaction with hexane and magnesium, followed by hydrolysis of the resulting ester. The introduction of the test solution into the reaction mixture will lead to the production of a colorless solution if it contains 6MTA or a colored solution if it does not contain 6MTA. The sequence for this synthesis is as follows:

1) Synthesize 6MTA by reacting magnesium with hexane and butyric acid
2)
