Coumaryl Triflate, a Versatile Building Block for the Modification of Coumarins and for Fluorescence Labeling

Abstract

Coumaryl triflate can be used for a wide range of substitution reactions, either under Pd-catalyzed conditions or via direct nucleophilic substitutions, and is therefore an ideal substrate for the fluorescence labeling of functionalized compounds, such as amino acids.

Key words

amino acids - carbonylation - coumarins - fluorescence labeling - palladium - substitution
