2-Phenylisopropyl and t-butyl trichloroacetamidates 1 and 2 are useful reagents for the esterification of N-protected aminoacids under mild neutral conditions. In the case of hydroxyl-containing amino acids, dialkylation occurs but no selectivity could be obtained.
2-苯基异丙基和叔丁基三氯乙酰胺酸酯1和2是在温和的中性条件下将N保护的氨基酸酯化的有用试剂。在含羟基的氨基酸的情况下,发生二烷基化,但是不能获得选择性。
