reduction of N-Boc-protected amino acid-derived secondary amides, avoiding the formation of overreduction and cyclic urea byproducts. The method is showcased by the efficient formal synthesis of NK-1 antagonist LY303870.
已经开发了选择性还原N -Boc保护的氨基酸衍生的仲酰胺的条件,从而避免了过度还原和环状脲副产物的形成。NK-1拮抗剂LY303870的有效形式合成证明了该方法。
