- PROCESSES FOR THE PREPARATION OF THIETANAMINE
-
The present invention provides processes for the preparation of compounds of formula (I) including processes comprising a. reacting a compound of formula (II) with a nucleophile in the presence of water to give a compound comprising a thietane moiety in which the carbon atom at the 3 position of the thietane moiety is bonded to a nitrogen atom; wherein the nucleophile is selected the group consisting of: N3-, a sulfonamide having two hydrogen atoms bound to the nitrogen atom, a diimide having a hydrogen atom bound to the nitrogen atom or an anion thereof, NH2OH and NH3; and b. when the nucleophile used in step a. is N3- or NH2OH, reacting the compound produced in step a. with a suitable reducing agent to give a compound of formula (I); or when the nucleophile used in step a. is a sulfonamide, reacting the compound produced in step a. with a reagent suitable for cleaving the S-N bond of the sulfonamide group to give a compound of formula (I); or when the nucleophile used in step a. is a diimide, reacting the compound produced in step a. with a reagent suitable for cleaving the C-N bond of the amide group to give a compound of formula (I). The invention also relates to intermediates useful for the preparation of compounds of formula (I).

- Selective synthesis of isomeric dithioglycerols
-
Reactions of 2,3-dibromopropan-1-ol and 1,3-dichloropropan-2-ol with elemental sulfur activated in the system hydrazine hydrate-2-aminoethanol at 30-35°C gave oligomeric polysulfides which were subjected to reductive cleavage with formation of individual dithioglycerol isomers. Activation of sulfur with the use of alkali gives rise to mixtures of isomeric products.
