functional group compatibility, with respect to side chain functionality of the amino acid (e. g. aliphatic and aromatic OH, (hetero)aromatic NH, amide NH, thioether), and the chiral amino acids do not undergo epimerization. The mechanism of the new amide synthesis has been studied.
Ñ -arylamino酰胺已经通过基于新方法被合成ñ -芳基胺活化成异硫脲,随后用下铁催化氨基酸反应。可以使用三组分反应与市售试剂叔丁基异氰化物和S-苯基苯硫代磺酸盐轻松地制备活化的N-芳基胺。相对于氨基酸(例如脂族和芳族OH,(杂)芳族NH,酰胺NH,硫醚)的侧链官能度,该方案显示出广泛的官能团相容性,并且手性氨基酸不发生差向异构化。已经研究了新酰胺合成的机理。
