Microwave irradiation accelerated rapid, efficient and high yield esterification of Boc-amino acid to Merrifield resin mediated by KF

摘要

A rapid and efficient procedure for the attachment of Boc-amino acid to Merrifield resin in the presence of potassium fluoride by flash heating under microwave irradiation has been described. Esterification rate acceleration and higher loadings are obtained significantly. Also, reaction times are reduced from the conventional 24 hr to 5-6 min duration under microwave irradiation.
