subsequent oxidation. This synthetic route is characterized by the wide range of aldehydes accessible, favorable step economy, mild reaction conditions, and tolerance of various functional groups, and it enables the facile generation of a range of KATs, for example, bearing halide, sulfide, acetal, or ester moieties. Moreover, this method was applied to the three‐step synthesis of various α‐amino acid analogues
酰基三氟硼酸钾(KAT)是通过铜(I)催化的醛化硼化和随后的氧化反应制得的。这种合成路线的特点是可利用的醛类广泛,有利的步骤经济性,温和的反应条件以及对各种官能团的耐受性,并且能够轻松生成各种KAT,例如带有卤化物,硫化物,乙缩醛,或酯部分。此外,通过使用天然氨基酸作为起始原料,该方法应用于三步合成各种在C末端带有KAT部分的α-氨基酸类似物。
