설명

애플리케이션

(R, R)-DIPAMP can be used:

• As a catalyst in the enantioselective [3+2] cycloaddition of γ-substituted allenoates with β-perfluoroalkyl enones and 3-butynoates with electron-deficient olefins to yield substituted cyclopentenes.
• To prepare its rhodium metal complexes, which are used as catalysts in asymmetric hydrogenation reactions.
