Taking direction well: Substituted phenylalanine derivatives were prepared by CH bond functionalization (see scheme). The syntheses are highly convergent and employ an N‐phthaloylalanine with a 2‐thiomethylaniline directing group. The use of an 8‐aminoquinoline directing group allows for the diarylation of methyl and the diastereoselective arylation of methylene groups.
方向很好:取代的苯丙氨酸衍生物是通过 C H 键功能化制备的(见方案)。合成是高度收敛的,并使用带有2-硫甲基苯胺导向基团的N-邻苯二甲酰丙氨酸。8-氨基喹啉导向基团的使用允许甲基的二芳基化和亚甲基的非对映选择性芳基化。
