The invention relates to a process for obtaining cis-4-hydroxy-6-methyl-5,6-dihydro-4H-thieno[2,3-b]thiopyran-7,7-dioxide, its enantiomers or mixtures thereof, by reduction of 5,6-dihydro-6-methyl-4H-thieno[2,3-b]thiopyran-4-one-7,7-dioxide with a reducing agent which generates hydride ions. The obtained compounds are useful as intermediates in the synthesis of chiral active ingredients.
Processes for the preparation of dorzolamide hydrochloride and an intermediate of Formula IV,
are provided.

The process for obtaining 4-(N-alkylamino)-5,6-dihydro-4H-thien-(2,3-b)-thiopyran-2-sulfonamide-7,7-dioxides (I) wherein R1 is H or C1-5 alkyl, and R2 is C1-5 alkyl, starts from the corresponding 4-(N-alkylamino)-5,6-dihydro-4H-thien-(2,3-b)-thiopyran-7,7-dioxides, and comprises protecting the alkylamine group, introducing a sulfonamide group and eliminating protecting group. Some compounds of formula (I) are inhibitors of the carbonic anhydrase and can be used in the treatment of elevated intraocular pressure.
