Description

General description

DHQ)₂PHAL is a modified cinchona alkaloid.

Application

(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.

Ligand for Sharpless Asymmetric Dihydroxylation employed in an enantioselective preparation of syn-3,5-hydroxycarboxylates from (E,E)- or (E,Z)-1,3-dienoates.

Physical form

Asymmetric dihydroxylation of unsaturated esters with trisubstituted C=C bonds.
