Esterification of Boc-Alanine and Boc-Aspartic acids by alcohols CnH2n+1OH and dio1s HO(CH2)nOH with imnobilized papain (XAD-7 or Sepharose) is discussed. Great improvement is obtained for the esterification of Boc-Ala-OH if papain is entrapped in XAD-7. For example no esterification is observed with 1-decanol if free papain is used whereas a 55% yield is obtained with papain immobilized on XAD-7.
