一般說明

DHQ)2PHAL is a modified cinchona alkaloid.

應用

Sharpless 不对称双羟基化的配体，用于由 (E,E)- 或 (E,Z)-1,3-二烯酸甲酯不对称制备 syn-3,5-羟基羧酸酯。
(DHQ)2PHAL may be used in the following processes:
  • As a catalyst Asymmetric and chemoselective N-allylic alkylation of indoles with Morita-Baylis-Hillman carbonates to form pyrrolo[1,2-a]indole and pyrrolo[3,2,1-ij]quinoline derivatives.
  • As a ligand for the osmium catalyzed-Sharpless asymmetric dihydroxylation step of (S)-a-benzoyloxy carboxylic acids multistep synthesis.
  • As a ligand for the carbamate based asymmetric aminohydroxylation of styrene derivatives to form N-carbamate protected R-arylglycinols.

外觀

具有三取代 C=C 键的不饱和酯的不对称双羟基化。

The enantioselective syntheses of several protected 4-substituted syn-3,5-dihydroxy carboxylic esters have been achieved from the corresponding achiral (E,E)- or (E,Z)-1,3-dienoates. The route relies upon an enantio- and regioselective Sharpless dihydroxylation and a palladium-catalyzed reduction to form gamma-substituted delta-hydroxy-1-enoates. The resulting

Asymmetric phase-transfer catalysis (PTC) has been recognized as a “green” alternative to many homogeneous synthetic organic transformations, and has found widespread application. Synthetically modified cinchona alkaloids are typical chiral organocatalysts used in asymmetric PTC.
