(Chemical Equation Presented) Catalytic and highly enantioselective Diels-Alder reaction of cyclic and acyclic dienes with r-phthalimidoacroleins provides cyclic α-quaternary α-amino acid precursors. The conformationally flexible chiral ammonium salt of H-L-Phe-L-Leu-N(CH 2CH2)2-reduced triamine with pentafluorobenzensulfonic acid is very effective as an asymmetric catalyst for the Diels-Alder reaction.
