Process for preparation of allyl sulfone derivatives and intermediates for the preparation

The present invention relates to a process for producing an allyl sulfone derivative represented by the formula (3): wherein Ar is an optionally substituted aryl group, and the corrugated line means either one of E/Z geometrical isomers, or a mixture thereof, which is an intermediate for producing vitamin A, which process is characterized by reacting an aryl sulfinic acid or a salt thereof represented by the formula (2): ArSO2M (2) wherein Ar is as defined above, and M is hydrogen atom, sodium atom or potassium atom, with an allyl halide derivative represented by the formula (1): wherein X is a halogen atom, and Ar and the corrugated line are as defined above.

Process for producing retinol and intermediate compounds for producing the same

There are disclosed a disulfone compound of formula (1): wherein Ar denotes an aryl group that may have a substituent, R1 denotes a hydrogen atom or a protective group of a hydroxyl group and the wavy ine means that the disulfone compound is an E or Z geometrical isomer or i mixture thereof,a method for producing the same,intermediate compounds therefore anda process for producing retinol through the disulfone compound.
