A catalyst-free sequential reaction involving hydrolysis and intramolecular aza-Michael addition was developed for synthesizing functionalized thiazolidines from 5-arylidenethiazolidin-4-ones at room temperature. A series of thiazolidine-5-carboxylic acids were prepared in good to excellent yields (up to 97% yield) and excellent diastereoselectivities (up to >20:1 dr). This methodology was applicable to the construction of derivatives of thiacloprid and flutianil with good yields.

A potassium salt useful in the production of N-substituted-1-alkylthio-2-nitroethenamines is produced by the reaction of the dipotassium salt of nitrodithioacetic acid with certain straight chain alkylamines, thereby converting only one of the KS-groups to an alkylamine group. The resulting monopotassium salt may be alkylated to produce the required N-substituted-1-alkylthio compound which may be reacted with a suitable amine to produce the histamine H2 -antagonist ranitidine.
