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.

(Chemical Equation Presented) A novel regioselective route for the synthesis of substituted and fused 3-chloro-2-(methylthio)quinoxalines through POCl3-mediated heteroannulation of a range of α-nitroketene N,S-anilinoacetals has been reported.
