General Description

DI-N-PROPYL SULFITE is a chemical compound with the formula (C3H7O)2SO2. It is a colorless liquid with a pungent odor, commonly used as a food preservative and antioxidant. DI-N-PROPYL SULFITE is also used in the production of pharmaceuticals and as a stabilizer in the synthesis of polymers. It is known for its ability to inhibit the oxidation of food products and extend their shelf life. However, it can cause irritation to the eyes, skin, and respiratory system, and should be handled with caution. Additionally, it has been associated with allergic reactions in some individuals.

ORGANOSULPHUR COMPOUNDS-LXIX OPTICALLY ACTIVE SULPHINATES: A NEW TYPE OF ENANTIOSELECTIVE ASYMMETRIC SYNTHESIS AND KINETIC RESOLUTION

Optically active sulphinates with the sulphur atom as a sole centre of chirality are prepared by two methods.The first involves the reaction of symmetrical sulphites with tert-butylmagnesium chloride in the presence of optically active aminoalcohols.This new asymmetric, enantioselective synthesis affords t-butylsulphinates with 40-70percent enantiomeric excess values.The second approach is based on a new type of kinetic resolution taking place when racemic sulphinates are reacted with tert-butylmagnesium chloride complexed by optically active alkaloid bases.Both the recovered sulphinates and sulphoxides formed in this reaction show moderate optical purities.
