Abstract: Here it is described the synthesis, antioxidant and antimicrobial activity determination of novel rel-($$5R,6S,7R$$5R,6S,7R)-6-benzoyl-7-phenyl-2-oxo-3,5,6,7-tetrahydro-2H-thiopyrano[2,3-d]thiazole-5-carboxylic acids. The target compounds were obtained in good yields from 5-arylidene-4-thioxo-2-thiazolidinones and $$\upbeta $$β-aroylacrylic acids via regio- and diastereoselective hetero-Diels–Alder reaction.… read more here.

Abstract: A novel domino strategy for the construction of intricate bridged bis-thiopyrano[2,3-b]indoles was disclosed, which involved one molecule of 3-formylchromones and two molecules of indoline-2-thiones, enabling the formation of four new bonds in a single operation.… read more here.
