Kinetic resolution of racemic 1-heteroarylalkanols by asymmetric esterification using diphenylacetic acid with pivalic anhydride and a chiral acyl-transfer catalyst is described. Molecular crystal of acridine and diphenylacetic acid and its absolute asymmetric photodecarboxylating condensation generates chirality in a two-component. The activation parameters for the racemization of a series of ortho-alkyl-substituted diphenylacetic acids are determined.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
Kinetic resolution of racemic 1-heteroarylalkanols by asymmetric esterification using diphenylacetic acid with pivalic anhydride and a chiral acyl-transfer catalyst is described. Molecular crystal of acridine and diphenylacetic acid and its absolute asymmetric photodecarboxylating condensation generates chirality in a two-component. The activation parameters for the racemization of a series of ortho-alkyl-substituted diphenylacetic acids are determined.
Solubility
Slightly soluble in water(0.13g/L).
Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.
