, p. 628 - 635 (2016/07/06)
The catalytic activity of different supported bifunctional thioureas on sulfonylpolystyrene resins has been studied in the nitro-Michael addition of different nucleophiles to trans-β-nitrostyrene derivatives. The activity of the catalysts depends on the l
One pot domino reaction accessing γ-nitroesters: Synthesis of GABA derivatives

Michael addition of 1,3-dicarbonyl compounds to nitrostyrenes is efficiently promoted by hydrotalcite [Mg-Al] to afford the respective γ-nitrodicarbonyl adducts. Differently, the addition of Meldrum's acid leads to a direct access of γ-nitroesters through a one pot domino process. GABA derivatives (+/-)-phenibut and (+/-)-baclofen were readily synthesized from the respective nitro adducts.
Immobilization of 1,5,7-triazabicyclo [4.4.0] dec-5-ene over mesoporous materials: An efficient catalyst for Michael-addition reactions under solvent-free condition

Immobilization of 1,5,7-triazabicyclo [4.4.0] dec-5-ene (TBD, a bicylic guanidine base) over mesoporous material like SBA-15 has been found to be an excellent catalyst for Michael-addition of β-nitro styrene with malonate. The reactions were performed und
