DCHA AS A NEW REAGENT FOR THE ESTERIFICATION OF OBSTINATED AMINO ACIDS BY THE MERRIFIELD'S RESIN
摘要:
The obstinated amino acid,Boc-Asn(or Boc-Gln),was directly anchored onto the Merrifield's resin using DCHA as the base in present reaction.The yield(71.88%)of Boc-Asn-OCH2-resin was much better than those(0-33.5%)using Cs2CO3,KOH,KF.DEA and TEA as the base.which are efficient reagents for other amino acids in the same reaction.
