HIGHLY ENANTIOSELECTIVE CATALYTIC DIELS-ALDER ADDITION PROMOTED BY A CHIRAL BIS(OXAZOLINE)-MAGNESIUM COMPLEX
Corey, E. J.,Ishihara, Kazuaki
, p. 6807 - 6810 (1992)
The new chiral bis(oxazoline) ligand 8 has been synthesized from (S)-phenylglycine and has been shown to form effective catalysts for enantioselective Diels-Alder addition in combination with ferric iodide, magnesium iodide or magnesium tetraphenylborate.Catalytic activation of the dienophile, 3-acryloyl-1,3-oxazolidine-2-one (4), in the magnesium system is proposed to involve tetrahedrally coordinated magnesium in a dispositive complex (10).
