용도

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.

참고

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.
