Asymmetric Michael addition catalyzed by D-glucose-based azacrown ethers

Novák,Tatai,Bakó,Czugler,Keglevich,Toke

, p. 424 - 426 (2001)

Novel sugar-based azacrown ethers with phosphinoxido-alkyl side chain (2a-e) have been synthesized. They show significant asymmetric induction as phase transfer catalysts in the Michael addition of 2-nitropropane to chalcone (95% ee) and to 3-fur-2-yl-1-phenyl-propenone (80% ee).
