Papaincatalyzedesterification of Boc-Ala-OH with various alcohols and diols under biphasic conditions was investigated. Long-chain diols HO(CH2)nOH gave good yields of esterification up to n=10 whereas the homologous alcohols CnH2n+1OH condensed well only for n = 2, 4, 6. Esterification with functionnalized primary alcohols is also described.
在双相条件下,研究了木瓜蛋白酶催化的Boc-Ala-OH与各种醇和二醇的酯化反应。长链二醇HO(CH 2)nOH在n = 10时具有良好的酯化收率,而同源醇C n H 2n + 1 OH仅在n = 2、4、6时能很好地冷凝。描述。
