摘要:A method for enhancing the purity of a desired compound comprising:Step (a) treating a crude reaction product which contains at least one desired compound, unreacted starting materials and/or byproducts with at least one bifunctional quenching agent that is capable of selective covalent reaction with unwanted byproducts, or excess reagents;Step (b) allowing the quenching agent to covalently react with unreacted starting materials and/or byproducts to afford a derivatized compound of the quenching agent: andStep (c) isolating the desired compound is described as well as novel quenching agents and methods for their use in the rapid purification of synthetic intermediates and products in synthesis, combinatorial chemistry, and automated organic synthesis.
