Document Type and Number:
Japanese Patent JPH11349585
Kind Code:
A
Abstract:
To provide an industrially useful production route for 2-oxo-1,3-dioxa-2- thiolane derivative.
In the production of 2-oxo-1,3-dioxa-2-thiolane that is represented by formula I (R is a hydrocarbon group which may be substituted), 1,2,3,4- butanetetraol represented by formula II is used as a starting substance and subjected to the reaction with a sulfonylation agent in the presence of a base in a solvent to sulfonate only the primary hydroxy group and give 1,4-dio-O- organosulfonyl-1,2,3,4-butanetetraol of formula III. Subsequently, the product is allowed to react with a thionylation agent thereby forming the thiolane skeleton.
