A chiral bicyclic guanidine was developed as a versatile Brønsted base catalyst for the enantioselective Michael reactions of dithiomalonates and β-keto thioesters using a range of acceptors including maleimides, cyclic enones, furanone and acyclic 1,4-dicarbonylbutenes.

DABCO catalysed highly diastereoselective cascade thia-Michael/aldol reaction was established for the construction of diversely functionalized tetrahydrothiophenes. Their in silico structure–function activities against MptpB have also been studied.
