Description

Technical Field

[0001] The present invention relates to the technical field of asymmetric synthesis, in particular to a kinetic resolution method for asymmetric catalytic hydrogenation of racemic beta-aryl esters or lactones. Background Art

[0002] Asymmetric hydrogenation of racemic esters using chiral catalysts has emerged as a promising strategy for the synthesis of chiral primary alcohols. Current successes primarily involve the asymmetric hydrogenation of racemic α-substituted esters, yielding β-chiral primary alcohols via dynamic kinetic analysis. There is only one reported case of asymmetric hydrogenation, the asymmetric hydrogenation of a racemic ester (patent document CN104355997 B), which enantioselectively synthesized a chiral primary alcohol with a distal stereocenter from the δ position via kinetic analysis.

[0003] This patent document (CN104355997 B) demonstrates the remarkable efficacy of chiral Ir-SpiroPAP catalyst in catalyzing the asymmetric hydrogenation of racemic δ-hydroxy esters through kinetic analysis, thereby achieving the enantioselective synthesis of chiral 1,5-diols and recovering the chiral δ-hydroxy esters with excellent enantioselectivity.

[0004]

[0005] However, the development of efficient catalytic protocols for the kinetically resolved asymmetric hydrogenation of racemic esters containing distant stereocenters has been hampered by the low hydrogenation reactivity of esters and the inherent complexity of resolving distant stereocenters. Kinetically resolved asymmetric hydrogenation of racemic esters containing distant stereocenters remains a formidable challenge.

[0006] To address this issue, the present invention provides an asymmetric hydrogenation reaction for racemic β-aryl esters or lactones containing a remote benzyl tertiary stereocenter. In the presence of a chiral Ir-SpiroPAP catalyst, a hydroxyl group is introduced into the racemic β-aryl ester or lactone, followed by hydrogenation, and enhanced chiral recognition through the lactone form. Summary of the Invention

[0007] The invention provides a highly efficient kinetic resolution method for asymmetric catalytic hydrogenation of racemic beta-aryl esters or lactones, and selectively synthesizes chiral gamma-aryl primary alcohols.
