Synthesis of novel P-stereogenic phenylphosphonamides and their application to Lewis base-catalyzed asymmetric allylation of benzaldehyde
摘要:
The synthesis of novel P-stereogenic phenylphosphonamides 3 and 11 via an intramolecular nucleophilic substitution of P-stereogenic phosphoramide 8 is described. These compounds were used as chiral Lewis basic catalysts for the asymmetric allylation of benzaldehyde, providing the corresponding homoallylic alcohol derivatives in up to 54% ee.
