Application

(+)-Bis[(R)-1-phenylethyl]amine can be used:
  • In the synthesis of β-amino acids.
  • In the preparation of chiral C(19)-C(26) and C(27)-C(32) moieties of scytophycin C.
  • To induce enantioselectivity in the deprotonation of prochiral ketones.
  • As a starting material for the synthesis of chiral phenolate ligands through Mannich condensation reaction.
  • In the synthesis of chiral phosphoramidite ligands.
  • To prepare chiral cyclic isoimidium salts, which are further used to synthesize chiral lactones through Diels-Alder reaction.

Diels-Alder reactions of cyclic isoimidium salts are described. The corresponding cycloadducts are obtained with high regio- and stereoselectivity. The use of homochiral cyclic isoimidium salts delivers cycloadducts with excellent diastereoselectivity (>99:1) that can be efficiently converted to enantiomerically pure lactones.

A study has been conducted to determine whether lithium magnesiates are feasible candidates for the enantioselective deprotonation of 4-alkylcyclohexanones. The commercially available chiral amine (+)-bis[(R)-1-phenylethyl]amine (2-H) was utilised to induce enantioselection. When transformed to its lithium salt and combined with
